I was surprised when Elon said this during his keynote. They're planning on making a full pivot to CyberCabs and RoboVans (their fully autonomous vehicles) and also concentrate on the Optimus robot. This seems like a premature move because people will still want to drive. He's betting everything on autonomy—typical high-risk Elon move. I hope it pays off!
Oh, that's concerning. I'd say even if it's 2060, considering how quickly AI is evolving, it might be enough time to solve a lot of challenges. I read that there are only a couple of areas of the world where birthrates are at the ideal rate of replacement.
It is definitely a race against time. I've heard SpaceX talks very recently about a moonbase settlement before Mars. That makes sense to use the moon as a "trial run" and staging area. Avi Loeb, the scientist in the news recently about 3I/Atlas, disagrees with outposts on Mars. He thinks we should build platforms in space and just begin building ships and habitats.
Yes there is a debate between the Martians & the O'Neilians with Elon on one side & Bezos on the other, although recently Elon has become open to O'Neilian ideas.
It is looking like SpaceX intends to provide enough launch capacity for both to happen simultaneously.
Indeed, because of the timing of Mars launch windows only every 26 months there will be huge launch capacity available for non-Mars projects during around 23 out of 26 months.
