The claim was that Musk's companies haven't "built" anything. Versions of Starship have clearly been built and launched, even if the project is still in development. It's a very real project and anyone can watch its developmental progress live: https://www.youtube.com/watch?v=mhJRzQsLZGg

I doubt you or anyone else would bet significant money that Starship won't reach orbit. If so, I'd be happy to accept.

For the record, I don't think you can point to any project even remotely equivalent in terms of capability or progress from Boeing, Lockheed, or ULA. I'd be happy if they were doing nearly as well as SpaceX.

My other examples: Starlink, Tesla, and Dragon have clearly been "built" and shipped. Starlink is the hands of consumers, is actively helping Ukraine for military and humanitarian purposes, Tesla has shipped millions of vehicles, and Dragon Crew had another successful rendezvous with ISS days ago.

I could spend a lot more time providing examples but consider these to be more than sufficient to disprove the claim that Elon Musk's companies haven't "actually built anything he announces" in "years".
