When we (the engineering team I work on) started using agents more seriously we were worried about this: that we'd speed up coding time but slow down review time and just end up increasing cycle time.

So far there's no obvious change one way or the other, but it hasn't been very long and everyone is in various states of figuring out their new workflows, so I don't think we have enough data for things to average out yet.

We're finding cases where fast coding really does seem to be super helpful though:

* Experimenting with ideas/refactors to see how they'll play out (often the agent can just tell you how it's going to play out)

* Complex tedious replacements (the kind of stuff you can't find/replace because it's contextual)

* Times where the path forward is simple but also a lot of work (tedious stuff)

* Dealing with edge cases after building the happy path

* EDIT: One more huge one I would add: anywhere where the thing you're adding is a complete analogy of another branch/PR the agent seems to do great at (which is like a "simple but tedious" case)

The single biggest potential productivity gain though I think is being able to do something else while the agent is coding, like you can go review a PR and then when you come back check out what the agent produced.

I would say we've gone from being extremely skeptical to cautiously excited. I think it's far fetched that we'll see any order of magnitude differences, we're hoping for 2x (which would be huge!).

  > The single biggest potential productivity gain though I think is being able to do something else while the agent is coding, like you can go review a PR and then when you come back check out what the agent produced.

  I've already passed through this phase and have given up on it. I'm sure everyone's experience will vary, but I just find it introduces either sufficiently more context switching or detracts sufficiently enough mental engagement that I end up introducing more errors, feeling miserable, or just straight up losing productivity and focus. This type of workflow is only viable for me if the cost of mistakes is low, the surface area for changes is small, or the mental context is the same between activities.

  The expectation that this is a serviceable workflow—I fear, and am experiencing—will ultimately just create more compressed timelines for everything, while quality, design, and job satisfaction will drop. Yes the code can be written while I look at a PR, but if it's a non-trivial amount of code or a non-trivial PR (which tends to become more frequent as more code generation and larger refactors are happening) then I'm just context switching between tasks I need to constantly re-zone in on, which is less gratifying and more volatile in a way that just hurts my mind and soul and money doesn't change in a meaningful way.

  That's not to say I'm not using them or seeing no productivity gains, but I'm not reclaiming that much time due to being able to anything concurrently, it's mostly reclaiming time I'd otherwise have procrastinated on something.

  This is where unnerving exhaustion comes from though.

  I know myself to be on the side of craftsmen. It does takes tons and tons of time to code, but I didn't get exhausted the way I do with AI. AI is productive, I am pro-AI. But boy is it a different kind of work beast.

  Ugh, sounds awful. Constantly context switching and juggling multiple tasks is a sure-fire way to burn me out.

  The human element in all of this never seems to be discussed. Maybe this will weed out those that are unworthy of the new process but I simply don't want to be "on" all the time. I don't want to be optimized like this.

    Often when you are solving a problem, you are never solving a single problem at a time. Even in a single task, there are 4-5 tasks hidden. you could easily put agent to do one task while you do another.

    Ask it to implement a simple http put get with some authentication and interface and logs for example, while you work out the protocol.

Why can't we figure out the right thing faster by building the wrong thing faster? Presumably we were gonna build the wrong thing either way in this example, weren't we?

I often build something to figure out what I want, and that's only become more true the cheaper it is to build a prototype version of a thing.

  Because usually the customer can only tolerate so many failed attempts per unit of time. Running your fitness function is often very expensive in terms of other people's time.

    Heh, depends on what you do. Many times the stakeholders can't explain what they want but can clearly articulate what they don't want when they see it.

    Generate a few alternatives, have them pick, is a tried and true method in design. It was way too expensive when coding was manual, so often you need multiple rounds of meetings and emails to align.

    If you don't think coding was the bottleneck, you're not thinking creatively about what's only now possible.

    It's not what you can do faster (well, it is, up to a point), but also what can you now, do that would have been positively insane and out of the question before.

    • pmontra

      today at 7:35 PM

      That's done by arranging a demo (the very old way) or (better) by deploying to a staging server. The customer meets with you for a demo not very often, maybe once per month, or checks what's on the staging server maybe a couple of times per week. They have other things to do, so you cannot make them check your proposal multiple times per day. However I concede that if you are fast you can work for multiple customers at the same time and juggle their demos on the staging servers.

  Fast prototyping helps when the prototype forces contact with the problem, like users saying "nope" or the spec collapsing under a demo. If the loop is only you typing, debugging, and polishing, you're mostly making a bigger mess in the repo and convincing yourself that the mess taught you something.

  Code is one way to ask a question, not proof that you asked a good one. Sometimes the best move is an annoying hour with the PM, the customer, or whoever wrote the ticket.

    I completely agree with this. I actually spent some time recently working on the design for a project. This was a side thing I spent months thinking about in my spare time, eventually spec'ing an API and data model.

    I only recently decided to take it on, given how capable Claude Code has become recently. It knocked out a working version of my backend pretty quickly, adhering to my spec, and then built a frontend.

    The result? I realized pretty quickly that the (IMO) beautiful design just didn't actually work with how it made sense for the product to work. An hour with the prototype made it clear that I needed to redesign from the ground up around a different piece to make the user experience actually work intuitively.

    If I had spent months of my spare time banging on that only to hit that wall, it would've been a much more demotivating experience. Instead, I was able to re-spec and spin up a much better version almost immediately.

    Has everyone always nailed their implementation of every program on the first try? Of course not. Probably what happens most times is you first complete something that sorta works and then iterate from there by modifying code, executing, observing, and looping back to the beginning. You can wonder about ultimately how much of your time/energy is consumed by the "typing code" part, and there's surely a wide range of variation there by individual and situation, but it's undeniable that it is a part of the core iteration loop for building software.

    I don't understand why GP's comment is so controversial. GP is not denying that you should maybe think a little before a key hits the keyboard as many commenters seem to suppose. Both can be true.

      No need to build three, you just have to quickly write a proof for which shapes can roll. You'll then spend x+y units of time, where y<<x, instead of 3*x units.

    Sometimes articulating the problem is all you need to see what the solution is. Trying many things quickly can prime you to see what the viable path is going to be. Iterating fast can get you to a higher level of understanding than methodical, deliberative construction.

    Nevertheless, it's a tool that should be used when it's useful, just like slower consideration can be used. Frontier LLMs can help significantly in either case.

        "Code writing speed" is just a superficial dismissal of AI without consideration as to whether AI is being used well or poorly for the task at hand. Saying that AI is the same as making people type faster, or that AI only produces slop, etc, is a very self limiting mindset.

  Sometimes you need to think slow to understand something. Offloading your thinking to a black box of numbers and accepting what it emits is not thinking slow (i.e. ponder) and processing the problem at hand.

  On the contrary, it's entering tunnel vision and brute forcing. i.e. shotgun coding.

• mooreds

  I think we can, in some cases.

  For instance, I prototyped a feature recently and tested an integration it enabled. It took me a few hours. There's no way I would have tried this, let alone succeeded, without opencode. Because I was testing functionality, I didn't care about other aspects: performance, maintainability, simplicity.

  I was able to write a better description of the problem and assure the person working on it that the integration would work. This was valuable.

  I immediately threw away that prototype code, though. See above aspects I just didn't need to think about.

    The typing referred to here is not "the typing part of coding" (fingers touching the keyboard), it's the whole coding (LLM is not a typing aid, it's a coding aid).

    And coding faster CAN help us understand the problem faster. Coding faster means iterating, refactoring, trying different designs - and seeing what does and doesn't work, faster.

  Pretty much, the article assumes people didn't build the wrong thing before AI. Except that did happen all the time and it just happened slower, took longer to realize that it was the wrong thing and then building the right thing took longer.

  It's funny, because you could actually take that story and use it to market AI.

  • Terr_

    today at 7:11 PM

    Sometimes being involved in the construction process allows you to discover all the (many, overlapping) ways it's the "wrong thing" sooner.

    In the long term, some of the most expensive wrong-things are the ones where the prototype gets a "looks good to me" from users, and it turns out what they were asking for was not what they needed or what could work, for reasons that aren't visually apparent.

    In other words, it's important to have many people look at it from many perspectives, and optimizing for the end-user/tester perspective at the expense of the inner-working/developer perspective might backfire. Especially when the first group knows something is wrong, but the second group doesn't have a clue why it's happening or how to fix it. Worse still if every day feels like learning a new external codebase (re-)written by (LLM) strangers.

  Can it help? Of course! But I think the question is too vague here and you're (presumably) unintentionally creating a false dichotomy. I'll clarify with the next responses

    > Why can't we figure out the right thing faster by building the wrong thing faster?
  

  The main problem is that solution spaces are very large. There are two general ways to narrow the solution space: directly and indirectly. Directly by things like thinking hard, digging down, and "zooming in". Indirectly by things such as figuring out what not to do (ruling things out).

  You can build a lot of wrong things that don't also help you narrow that solution space. The most effective way to "build the wrong thing" in an informative way is to first think hard and understand your solution space. You want to build the right wrong thing. The thing that helps you rule out lots of stuff. But if you are doing it randomly then you aren't doing this effectively and probably wasting a lot of time. You probably are already doing this but not thinking too much about this explicitly, but if you think explicitly you'll improve on this.

    > Presumably we were gonna build the wrong thing either way
  

  You always build the "wrong" thing. But it is about how wrong you are. Despite being about physics, I think Asimov's Relativity of Wrong[0] (short essay) is pretty relevant here and says everything I want to say but better. It is worth the read and I come back to it frequently.

    > I often build something to figure out what I want
  

  Yes! But this is not quite the same thing. I do this too! I never know the full details of the thing I want before I start building. I'm not sure that's even possible tbh. You're always going to discover more things as you get into the details and nuance. But that doesn't mean foresight is useless either.

    Analogy
    -------
  

  Let's say I'm somewhere in the middle of America and I want to get to NYC. Analogous to your framing you are saying "why can't moving faster help us get there faster?" Obviously it can! BUT speed is meaningless without direction. You don't want speed, you want velocity. If you start driving as fast as possible in a random direction you're equally likely to head in a direction that increases your distance than one that decreases. And you are very unlikely to head in a good direction. Driving fast in the wrong direction significantly increases harm than were you to drive slowly in the wrong direction.

  So what's the optimal strategy? Find a general direction (e.g. use the sun or stars/moon) to figure out where "east"(ish) is, start driving relatively slowly, refine your direction as you get more information about the landscape, speed up as you gain more information. If you can't find a general direction you should slowly meander, carefully taking in how the landscape/environment is changing. If it is very unchanging, then yeah, speedup, but only until you find a region that becomes more informative, then repeat the process.

  If we already had perfect information about how to get to NYC then just drive as fast as fucking possible. But if we don't have that information we need a completely different strategy. Thus, t̶y̶p̶i̶n̶g̶ driving speed isn't the bottleneck.

  Speed doesn't matter, velocity does

  > Why not? Why can't faster typing help us understand the problem faster?

  Why do you need to type at all to understand the problem?

  I write my best code when I'm driving my car. When I stop and park up, it's just a case of typing it all in at my leisure.

I read this book last year and this application is spot on. There is a point in the narrative when the company automates a step in their manufacturing using an expensive machine and it has the effect developed here: the next step in the process is backed up further.

The points specific to software where it might not even be producing in-spec is also very good.

Comments that cite the solo dev/prototype case are of course not what this is getting at, but it's one good use of quick generation.

I would extend this article by saying what The Goal says, namely that the goal of every firm is to make money, and everything is intermediate to that. So whether or not software architecture is grade-A or grade-C, it's only ever in this subservient role to the firm's goal.

> Someone approves a PR they didn’t really read. We’ve all done it (don’t look at me like that). It merges. CI takes 45 minutes, fails on a flaky test, gets re-run, passes on the second attempt (the flaky test is fine, it’s always fine, until it isn’t and you’re debugging production at 2am on a Saturday in your underwear wondering where your life went wrong. Ask me how I know… actually, don’t). The deploy pipeline requires a manual approval from someone who’s in a meeting about meetings. The feature sits in staging for three days because nobody owns the “get it to production” step with any urgency.

This is the company I (soon no longer) work at (anyone hiring?).

The thing is that they don’t even allow the use of AI. I’ve been assured that the vast majority of the code was human-written. I have my doubts but the timeline does check out.

Apart from that, this article uses a lot of words to completely miss the fact that (A) “use agents to generate code” and “optimize your processes” are not mutually exclusive things; (B) sometimes, for some tickets - particularly ones stakeholders like to slide in unrefined a week before the sprint ends - the code IS the bottleneck, and the sooner you can get the hell off of that trivial but code-heavy ticket, the sooner you can get back to spending time on the actual problems; and (C) doing all of this is a good idea completely regardless of whether you use LLMs or not; and anyone who doesn’t do any of it and thinks the solution is to just hire more devs will run into the exact same roadblocks.

I'm a solo dev. In fact I'm hardly a dev; it's just a helpful skill. Code writing speed IS a problem, because it takes valuable time away from other tasks. A bit like doing the dishes.

I just set up Claude Code tonight. I still read and understand every line, but I don't need to Google things, move things around and write tests myself. I state my low-level intent and it does the grunt work.

I'm not going to 10x my productivity, but it'll free up some time. It's just a labour-saving technology, not a panacea. Just like a dishwasher.

  Exactly!

  I've been working on a side project that I started in 2020. If I wanted to implement a new feature it was: - Wait for regular work hours to wrap up around 5 or 6 PM - Get dinner and rest / relax until around 8 or 9 PM - Open up the editor, think about the problem, Google things, read stack overflow which gets it 95% of the way there, Google more, dig deeper into the docs finally find what I needed - Write a function, make some progress, run into another roadblock, repeat previous point - Look up and it's now 1AM. I should write tests for this, but I'll add that to the backlog - Backlog only ever grows

  Now with AI I describe what I want, it does the grunt work likely cleaner than I ever could, adds tests and warns me about potential edge cases.

  I don't know about 10x, but I'm releasing new features that my client cares about faster and I have more time to myself.

  All of the negativity around AI writing code sounds like people who would say "You can't trust the compiler, you need to write the machine code yourself"

  Will AI fuck up? Yes But I'm the human in the chair guiding it, and learning myself how better to prompt it to keep it from those fuck ups with every iteration.

  The intention of the title is to say your main problem. The problem separating you from $PROFIT$:

      1. Idea
      2. ???
      3. Profit
  

  Coding effectively is definitely one problem. And you're right that AI helps with that problem. But for startups, side-hustles, VC-pitches and the inner-workings of companies (HN crowd) coding was never the problem.

  edit to add: So for people working on professional software teams, the discussion is how a hyper-increase in raw code production affects everything down stream. There are many moving parts to building stuff and selling it to people. So there's not a 1:1 line to more code = better outcome from the system level view. It's not clear, at least.

    I'd say you're 180° wrong. Getting to an MVP fast is the most immediate problem when you've started a startup. Iterating on ideas fast is the most immediate problem once you've released your MVP. You need an MVP to get users, and you need to to iterate to find product-market fit. Perfectly crafted code is a luxury problem you can't afford in the early stages.

    • apsurd

      today at 8:26 PM

      This isn't in defense of perfectly crafted code. It's about NO CODE. Do not write (ai-moar) code! It's not the code that is the problem.

      I understand the need for MVP to bring an idea into reality. It's the feedback that's valuable not the code. This is not about the code. So why is the argument "write more code"?

      In any case, I have yet to create a product on my own that has done well financially. So what the hell do I know. If you have, then I should probably listen to you. But I have worked on teams for successful companies and in my career, the best advice I can give to an engineer is that your code matters, do a good job and care about what you make; also it's not about the code.

  This I think is pretty spot on. I still have to review the code ideally line by line. It is like templates, generators, etc. they help and do make things faster but 10x isnt gonna happen unless requirement gathering also 10x which so far, ai has had no impact on.

      Eventually after AI tech gets mature enough, we will be able to save EVEN MORE energy by getting rid of all the people.

Code-writing speed is not a bottleneck when the stakes are high. Sometimes, it's better to slow down, plan ahead, and consider the consequences because the cost of a failed iteration is too great.

Take the way AI is being developed as an example. People rush to build giant agents in giant datacenters that are aligned to giant corporations and governments. They're building the agentic organism equivalent of machiavellian organizations, even though they'd be better off building digital humans that are aligned to individual humans that run on people's gaming PCs at home. They will find out that the former is the wrong architecture, but the cost of that failed iteration is the future of human civilization, and nobody gets a second try.

Of course, this is an extreme example on one end of the scale. On the other end, it wouldn't matter at all if you're building a small game for yourself as a weekend project with no users to please or societal impacts to consider.

Yeah, we again have a solution (LLMs) in search of problems.

Proper approach to speeding things up would be to ask "What are the limiting factors which stops us from X, Y, Z".

• raw_anon_1111

  today at 7:29 PM

  This is categorically not true. For almost all of my 30 years it’s been

  1. Talk to the business, solve XYProblems, deal with organization complexity, learn the business and there needs.

  2. Design the architecture not just “the code”, the code has to run on something.

  3. Get the design approve and agree on the holy trinity - time/cost/budget

  4. Do the implementation

  5. Test it for the known requirements

  6. Get stakeholder approval or probably go back to #4

  7. Move it into production

  8. Maintenance.

  Out of all those, #4 is what I always considered the necessary grunt work and for the most part even before AI especially in enterprise development where most developers work has been being commoditized in over a decade. Even in BigTech and adjacent codez real gud will keep you as a mid level developer if you can’t handle the other steps and lead larger/more impactful/more ambiguous projects.

  As far as #5 much of that can and should be done with automated tests that can be written by AI and should be reviewed. Of course you need humans for UI and UX testing

  The LLMs can do a lot of the grunt work now.

  • zelphirkalt

    today at 8:00 PM

    I see step 4 as interwoven with other steps. The implementation ideally takes into consideration the domain and while implementing, potentials for flexibility are potentially revealed, to be taken advantage of, "without programming ourselves into a corner". Implementation also is of course related to maintenance. Maintenance already needs to be taken into account. How easy is it to adapt the system we are building later?

    This all happens while we are at the implementation stage and impacts all other aspects of the whole thing. It is a grunt work, but we need elite grunts, who see more than just the minimal requirements.

    • raw_anon_1111

      today at 8:12 PM

      I’ve been going on about this in another thread in a separate post. That’s where modularity comes in. From code I write to teams (or multiple teams back in the day). I always enforce micro services. Not always separately deployable micro service, they could be separate packages with namespace/public/private accessibility.

      Even if you do have not so good developers, they can ramp up quickly on one specific isolated service and you can contain the blast radius.

      This isn’t a new idea. This was the entire “API mandate” that Bezos had in 2002. s3 alone is made up of 200+ micro services

As human developers, I think we're struggling with "letting go" of the code. The code we write (or agents write) is really just an intermediate representation (IR) of the solution.

For instance, GCC will inline functions, unroll loops, and myriad other optimizations that we don't care about. But when we review the ASM that GCC generates (we don't) we are not concerned with the "spaghetti" and the "high coupling" and "low cohesion". We care that it works, and is correct for what it is supposed to do. And that it is a faithful representation of the solution that we are trying to achieve.

Source code in a higher-level language is not really different anymore. Agents write the code, maybe we guide them on patterns and correct them when they are obviously wrong, but the code is merely the work-item artifact that comes out of extensive specification, discussion, proposal review, and more review of the reviews.

A well-guided, iterative process and problem/solution description should be able to generate an equivalent implementation whether a human is writing the code or an agent.

• pbasista

  Of course we do not. Because there is no need. The process of compiling higher order language to assembly is deterministic and well-tested. There is no need to continue reviewing something that always yields the same result.

  > We care that it works, and is correct for what it is supposed to do.

  Exactly. Which is something we do not have with an output of an LLM. Because it can misunderstand or hallucinate.

  Therefore, we always have to review it.

  That is the difference between the output of compilers and the output of LLMs.

    • perlgeek

      today at 8:21 PM

      In the 12+ years I've been a professional developer, I can only remember two bugs that were caused by the compiler / interpreter, everything else were logic bugs, oversights, 3rd-party libraries, misunderstanding of the requirements, internal contradictions in the requirements etc.

      So that's maybe 0.1% of all the bugs I've touched.

      In that sense, code generation isn't really an interesting source of bugs for the discussion at hand.

    • leptons

      today at 8:14 PM

      If the "bug" shows up every time in the output given the same input, then it definitely is deterministic.

      Just because there are bugs does not mean a compiler is non-deterministic. I looked through a bunch of the bug reports and there is nothing there that can't be fixed to make it deterministic.

      You can't fix an LLM to be absolutely deterministic, but you can fix a compiler.

  • qalmakka

    today at 7:52 PM

    This. The comparison between compilers and LLMs is so utterly incorrect, and yet I've heard it multiple times already in the span of a few weeks. The people suggesting this are probably unaware of the fact that Turing complete languages follow mathematical properties not just vibes. You can trust the output of your compiler because it was thoroughly tested to ensure it acts as a Turing machine that converts one Turing complete language (C, C++, whatever) into another Turing complete language (ASM) and there's a theorem that guarantees you that such a conversion is always possible. LLMs are probabilistic machines and it's grossly inappropriate to put them in the same category as compilers - it would be like saying that car tires and pizzas are similar because they're both round and have edges.

    Right? That's the only reason that "coding with LLMs" works at all (believe me, all at the same time, I am wowed by LLMs, and carry a healthy level of skepticism with respect to their ability as well). You can prompt all you want, let an Agent spin in a Ralph loop, or whatever, but at the end of the day, what you're checking into Git is not the prompts, but the formalized, codified artifact that is the bi-product of all of that process.

  • yason

    today at 7:45 PM

    Somewhat ironically, perhaps a formal, deterministic programming language (in its mathematical-kind of abstract beauty) is the outlier in the whole soup. The customers don't know what they need, we don't know what we ought to build, and whatever we build nobody knows how much of it is the right thing and what it actually does. If the only thing that causes people to sigh is the requirement to type all that into a deterministic language maybe at some point we can just replace that with a fuzzy, vague humanly description. If that somehow produces enough value to justify the process we still won't know what we need and what we're actually building but at least we can just be honestly vague about it all the way through.

  In my experience it doesn't really work that way. It's somewhat akin to a house that's undergone multiple remodels. You eventually run out of the house's structural capacity for more remodeling and you have to start gutting the interior, reframing, etc. to reset the clock.

  At least today the coding agents will cheat, choose the wrong pattern, brute force a solution where an abstraction or extra system was needed, etc. A few PR's won't make this a problem, but after not very long at all in a repo that a dev team is constantly contributing to (via their herds of agents) it can get pretty gnarly, and suddenly it looks like the agents are struggling with tech debt.

  Without this, we quickly drift into treating computers and computer programs as even more magic, than we already do.

        Compilers can generate wrong output in many different ways. And they're all analogous to the same ways that a sophisticated LLM can generate wrong outputs.

        The compiler relies on:

        * Careful use of the ENV vars and CLI options

        * The host system, or the compilation of the target executable (for cross-compiling)

        * It relies on the source code specifically

        How is this really different from careful prompt engineering, and an extensive proposal/review/refine process?

        They are both narrowing the scopes and establishing the guardrails for what the solution and final artifact will be.

        > proposal/review/refine process

        This is essentially what a sophisticated compiler, or query optimizer (Postgres) does anyway. We're just doing it manually via prompts.

          So different that those concepts don't even exist.

          I don't have to carefully prompt my compiler in case it might misinterpret what I'm saying. My compiler comes with a precisely specified language.

          I never, ever, review the output of my compiler.

        • tcmart14

          today at 7:55 PM

          And none of that means it isn't non-deterministic. Compilers still satisfy the, given the exact same environment and input, you get the same output. It doesn't matter the number of inputs. So long as f(3, 2) always gives 5, it's deterministic. Doesn't matter what f(x,y) does so long as it always gives the same output per input. LLM generation does not do this. If given f(3,2), sometimes it says 5, sometimes 6, sometimes 1001, sometimes 2.

          And we are talking compilers, not query optimizers, so I don't really care what they do.

  The more complex the code becomes, iteration after iteration by the AI, it keeps adding more and more code to fix simple problems, way more than is reasonably necessary in many cases. The amount of entropy you end up with using AI is astonishing, and it can generate a lot of it quickly.

  The AI is going to do whatever it needs to do to get the prompt to stop prompting. That's really its only motivation in its non-deterministic "life".

  A compiler is going to translate the input code to a typically deterministic output, and that's all it really does. It is a lot more predictable than AI ever will be. I just need it to translate my explicit instructions into a deterministic output, and it satisfies that goal rather well.

  I'll trust the compiler over the AI every single day.

  I might be more charitable. I'd say something like "Companies genuinely want good code but weigh the benefits of good code (future flexibility, lower maintenance costs) against the costs (delayed deployment, fewer features)."

  Each company gets to make the tradeoffs they feel are appropriate. It's on technical people to explain why and risks, just like lawyers do for their area of expertise.

• dannersy

  today at 7:53 PM

  They don't care about good code, but they do pay people a lot of money to care about good code. If the people you hired didn't care, our software quality would be worse than it is. And since people are caring less in the face of AI, it is getting worse.

Ultimately the conclusion will be humans are the bottleneck somewhere along the path and no amount of agents will replace that person because you don't run businesses on vibes and code.

I think one of the biggest gains of AI is the second order effects. And maybe a bit in the third order as well. When coding with Claude, I can focus on the architecture, the big picture of the implementation, while Claude takes care of the details. Every function for which I don't have to remember the order of the arguments anymore, is a little bit extra brain power I can dedicate to thinking about the solution. I can focus on what matters, and I can focus for longer. I find that remembering argument order is much more tiresome than thinking through complex interactions(because the latter is fun, while the former is boring)

Then there's the speedup. A smaller team can now achieve what a larger team was needed for before. This means less communication overhead, in theory fewer and/or shorter meetings. Which all translates to me spending more time and more energy on thinking about the solution. Which is what matters.

How do people ensure that AI don't produce subtle and stupid mistakes that humans usually don't make, like the one in Amazon that deleted the entire production deployment?

When a person writes code, the person reasons out the code multiple times, step by step, so that they don't make at least stupid or obvious mistakes. This level of close examination is not covered in code review. And arguably this is why we can trust more on human-written code than AI-produced, even though AI can probably write better code at smaller scale.

In contrast, Amazon asked senior engineers to review AI-generated code before merging them. But the purpose of code review was never about capturing all the bugs -- that is the job of test cases, right? Besides, the more senior an engineer is in Amazon, the more meetings they go to, and the less context they have about code. How can they be effective in code review?

  Right... Because Humans have never ever accidentally rm -rf'd a production system in the wrong spot?

  GitLab has entered the chat.

  Or that time an S3 developer purged more than intended, causing internet outages.

  All the above are from 2017.

  Humans make mistakes. Anyone arrogant enough to think they only write perfect code is delusional.

  We are holding AI to higher standards than we hold humans, who are just as fallible if not worse.

  QA your software, stop letting developers test changes.

cries in Factorio

My problem when writing code is mainly executive dysfunction; I constantly succumb to the temptation to take the easy way and do it properly later, and later never comes. For some reason, using a coding agent seems to alleviate this. Things get done the way I think they should be done, not just in a way that's "good enough for now."

I don’t agree. I have built Replit clone alone in months. They have hundreds of millions of funding…

Btw: https://playcode.io

It's unfair to characterize AI as 'code writing / completion' - it's at minimum 1/4 layer of abstraction above that - and even just 'at that' - it's useful.

So 'writing helper' + 'research helper' + 'task helper' alone is amazing and we are def beyond that.

Even side features like 'do this experiment' where you can burn a ton of tokens to figure things out ... so valuable.

These are cars in the age of horses, it's just a matter of properly characterizing the cars.

Completely agree with the premise. The bottleneck in most teams I've worked with isn't typing speed or even coding speed - it's the feedback loop between 'I think this is right' and 'this is actually right in production.'

The biggest time sink is usually debugging integration issues that only surface after you've connected three services together. Writing the code took 2 hours, figuring out why it doesn't work as expected takes 2 days.

I've found the most impactful investment is in local dev environments that mirror production as closely as possible. Docker Compose with realistic seed data catches more bugs than any amount of unit testing.

I can really relate to this. At the same time I’m not convinced cycle time always trumps throughput. Context switching is bad, and one solution to it is time boxing, which basically means there will be some wait time until the next box of time where the work is picked up. Doing time boxing properly lowers context switching, increases throughput but also increases latency (cycle time). It’s a trade-off. But of course maybe time boxing isn’t the best solution to the problem of context switching, maybe it’s possible to figure out a way to have the cookie and eat it. And maybe different circumstances require a different balance between latency and throughput.

« you are speeding up the rate at which you build the wrong thing »

Yeah. I keep seeing this over and over with devs who use LLMs. It's painful to watch.

if you ever played factorio this is pretty clear.

While reading articles like this, I feel like we're just in the "denial" stage. We're just trying to look for negatives instead of embracing that this is a definite paradigm shift in our craft.

Correct, but I'd frame it to confused leaders a bit differently. Because we made this part easier, we've increased how critical, how limiting, other steps/functions are. Data's more valuable now. QA is more valuable now. More teams need to shift more resources, faster.

I think it's more abstraction problem.

You could write more code, but you also could abstract code more if you know what/how/why.

This same idea abstracts to business, you can perform more service or you can try to provide more value with same amount of work.

The word typing is wrong.

It is not about the speed of typing code.

Its about the speed of "creating" code: the boilerplate code, the code patterns, the framework version specific code, etc.

This entire piece sounds AI written (or at minimum, heavily AI edited) with its "punchy" writing style LLMs love, negative parallelisms galore (see blockquotes 2, 3, 5), invented concept labels ("your calendar is a load-bearing wall" ???), attempts at humor sprinkled in. What a joke of a post.

  Also add a PR reviewer bot. Give it authority to reject the PR, but no authority to merge it. Let the AIs fight until the implementation AI and the reviewer AI come to an agreement. Also limit the number of rounds they're permitted to engage in, to avoid wasting resources. I haven't done this myself, but my naive brain thinks it's probably a good idea.

  The problem is most of the people we have spent the last 20 years hiring are bad at code review.

  Do you think the leet code, brain teaser show me how smart you are and how much you can memorize is optimized to hire the people who can read code at speed and hold architecture (not code but systems) in their head? How many of your co-workers are set up and use a debugger to step through a change when looking at it?

  Most code review was bike shedding before we upped the volume. And from what I have seen it hasn't gotten better.

Amdahl's law applies regardless of whether you are believe in it or not

The idea that LLMs don't significantly increase productivity has become ridiculous. You have to start questioning the psychology that's leading people to write stuff like this.

  aren't we all...

Eh code doesn't have a lot of value. Especially filling methods between signatures and figuring out the dependencies exact incantation is mechanistic and definitely time better spent doing other things.

A lot of these blog start from a false premise or a lack of imagination.

In this case both the premise that coding isn't a bulk time waste (and yes llm can do debugging, so the other common remark still doesnt apply) is faulty and unsubstantiated (just measure the ratio of architects to developers) but also the fact that time saving on secondary activities dont translate in productivity is false, or at least it's reductive because you gain more time to spend on doing the bottlenecked activity.

Thank you. 100%.

If I can offload the typing and building, I can spend more energy understanding the bigger picture

One of the main reasons I like vim is that it enables me to navigate code very fast, that the edits are also quick when I've decided on them is a nice convenience but not particularly important.

Same goes for the terminal, I like that it allows me to use a large directory tree with many assorted file types as if it was a database. I.e. ad hoc, immediate access to search, filter, bulk edits and so on. This is why one of the first things I try to learn in a new language is how to shell out, so I can program against the OS environment through terminal tooling.

Deciding what and how to edit is typically an important bottleneck, as are the feedback loops. It doesn't matter that I can generate a million lines of code, unless I can also with confidence say that they are good ones, i.e. they will make or save money if it is in a commercial organisation. Then the organisation also needs to be informed of what I do, it needs to give me feedback and have a sound basis to make decisions.

Decision making is hard. This is why many bosses suck. They're bad at identifying what they need to make a good decision, and just can't help their underlings figure out how to supply it. I think most developers who have spent time in "BI" would recognise this, and a lot of the rest of us have been in worthless estimation meetings, retrospectives and whatnot where we ruminate a lot of useless information and watch other people do guesswork.

A neat visualisation of what a system actually contains and how it works is likely of much bigger business value than code generated fast. It's not like big SaaS ERP consultancy shops have historically worried much about how quickly the application code is generated, they worry about the interfaces and correctness so that customers or their consultants can make adequate unambiguous decisions with as little friction as possible.

Understanding the problem is easier for me experienced with engaging with solutions to the problem and seeing what form they fail in. LLMs allow me to concretize solutions so that pre-work simply becomes work. This allows me to search through the space of solutions more effectively.

It’s definitely going to create a lot of problems in orgs that already have an incomplete or understaffed dev pipeline, which happen to often be the ones where executive leadership is already disconnected and not aware of what the true bottlenecks are, which also happen to often be the ones that get hooked by vendor slide decks…

he’s treating “systems thinking” and architecting software like it’s some sacred, hard to automate layer that AI apparntly sucks at ..

These “LLM programming ain’t nothing special” posts are becoming embarrassing for the authors who - due to their anti AI dogmatism - have no idea how truly incredibly fast and powerful it’s become.

Please stop making fools of yourselves and go use Claude for a month before writing that “AI coding ain’t nothing special” post.

Ignorance of what Claude can actually do means your arguments have no standing at all.

  What makes you think they haven't? I agree with them and I've been heavily using Claude / Codex for a while now. And I'm slowly trying to use AI more selectively because of these concerns.

    Ok tell me tangibly what you are programming, what you ask it to do and I’ll do similar and we can compare outcomes.

> I once watched a team spend six weeks building a feature based on a Slack message from a sales rep who paraphrased what a prospect maybe said on a call. Six weeks. The prospect didn't even end up buying. The feature got used by eleven people, and nine of them were internal QA. That's not a delivery problem. That's an "oh fuck, what are we even doing" problem.

I have very much upset a CEO before by bursting his bubble with the fact that how fast you work is so much less important than what you are working on.

Doing the wrong thing quickly has no value. Doing the right thing slowly makes you a 99th percentile contributor.

people can have more than one problem

Because the way the world is currently and this is trending, let me jump in and save you a lot of time:

Expedience is the enemy of quality.

Want proof? Everyone as a result of “move fast and break things” from 5-10 years ago is a pile of malfunctioning trash. This is not up for debate.

This is simply an observation. I do not make the rules. See my last submission for some CONSTRUCTIVE reading.

Bye for now.

I'm cynical but kinda surprised that so many mgmt types are rah-rah AI as "we're waiting for engineering... sigh" has been a very convenient excuse for many projects and companies that I've seen over past 25 years.

  Absolutely. Everyone loves a roadblock that someone else needs to clear, giving back some time to breathe and think about the problem a bit.

  This only works in large companies. In startups this is how you run out of money.

No one there is solving a problem. The AI bros are hooking a new generation (NG) on _their_ set of crutches, without which NG "is not coding (living) up to their true potential". Nothing personal, just business.

PS. The tech bros tried to do exactly that to millennials, but accidentally shot boomers instead.

  The thing is that speed in building stuff doesn't really help. What you want is a model and a simulation framework. In the traditional way, you usually start with a simple model and a simple framework. Then when you add a new parameter, you adapt the framework and once you've found a balanced set of inputs, you think which new parameter you want to add. This iteration leads to a great understanding of the model and the behavior of the system that implements it.

  LLM usage is usually a build of the system for the full parameter set. The speed increase is countered by the fact that there's no understanding of the system and the simulation space is so large that the user don't really bother to explore it. There's been a lot of talks about having a full test suite for simulation, but they are discrete and only prove specific points in the input space (There's a lot of curves that can pass through a finite set of points)

            Bigger tells are the other two green accounts posting multiple top level comments in this topic that are nearly identical. Perhaps the programmer had an off by one error somewhere.

            I count at least three top level posters, if not as many as five, in this topic that are LLMs. The real absurdity is devnotes responding to myylogic, who are both LLMs.

The blog isn't even necessarily anti-AI yet the majority of responses here are defending it like the author kicked their dog.

The sentiment that developers shouldn't be writing code anymore means I cannot take you seriously. I see these tools fail on a daily basis and it is sad that everyone is willing to concede their agency.
