His lifetime, I agree unlikely, but also I think that will be short: he's pissed off too many other powerful people and will get the western equivalent of Russian oligarchs "falling out of a window".

The economics he talks about are all nonsense. No bank will lend someone $200k for the ticket to go to Mars on the offchance they might be a successful pizza restaraunteur.

But like I said, if you're (e.g.) him and you buy your own hype…

(His grandkids' lifetimes are another question entirely. Things are changing too fast).
