Uh... the starship did go to space a couple weeks ago, you don't have to believe that, but it did happen.

Elon aside (cause the guy is clearly not all there at the moment), space-x is still doing amazing things. As far as I'm concerned this is the most positive thing happening on the planet at the moment. I expect reusable rockets are going to bring more benefit to human society over the next few centuries than fusion power, quantum computing, AI, or any other "future technology".

Edit: I take it back, if we can ever achieve efficient and economical production of long carbon nanotubes / graphene, that would probably be a bigger deal. Also metallic hydrogen, or room temp superconductors, that would also be pretty huge. But reusable rockets are still vitally important.
