Srsly?
Just to be very clear about Starship: We have a very limited amount of payload we are sending up in space every year.
The biggest jump in payload is starlink itself. Starlink though doesn't scale very well. V2 can only handle a certain amount of customers and has only a lifetime of 5 years.
Space-X has to build Starship to even being able to send v3 up to increase the margin of this setup. But even then, every 5 years that thing has to be replaced and new build.
Every mobile tower, fiber cable etc. underground has a lot higher lifetime than that.
Starlink also has the issue of latency handover. Every few minutes you have to do a handover which leads to package loss. I can't do a Teams Call through Starlink fyi.
And Starlink already exists and is relativly affordable despite that, they only have 9-10 Million customers and they had to increase the price.
And while all of this 'magic no one gets' is happening, Starship hasn't profen non leo orbit with proper payload AND reusability. Without reusability, they will not get the costs down that much anymore. Its already relativly cheap.
And in parallel all of this 'trillion dollar future margin magic' gets opposition by other companies like eutelsat and Amazon.
Ah yes the world changing product of starlink mobile. Which doesn't get booked in the USA, is slow and needs a lot of energy. Whatever you think this is, 500km mobile range is 500km and this on a planet were normal people already have a very very well working mobile setup for at least 10 years by now.
Is space-x some kind of business gap? yes sure. Will they make billions with this? Depending on other companes, yeah sure. Is it a trillion dollar business? No
Yes yes i'm fully unaware of this.
Btw. Musk def sells you the story of Mars and dyson sphere and stuff to keep the magic but while he does all of this, he rents out colossus 1 and 2 to his competitors because he is unable to sell his OWN AI product.
