Remember "Mars colony in 20 years" for the last 20 years or so? Well, some bad news about that. Or maybe good news if you're tired of bullshit peddling.

That's right. Seems 
's current culture war fixations have made him sufficiently less interested in his older bullshit promises.
He will grift on, but seems he's losing interested in the space grift. He's posting cringe Gambo "AI" videos showing Gambo's favorite objectified SV victim and mistreated actress being a DJ at a Gambo-setting dance party instead (not linking that shit, look for it if you dare).
The light of consciousness may not extend to the stars within his lifetime by his own admission, which means if it ever does it won't include his dim smoldering light nor will it be his bigoted and emotionally poisonous consciousness. 
I would say his pivot to culture wars is in part because he wants to distract people from his promises. I don't think there is much more he can offer in the name of perverted progress. He already has his hands in spacex, hyperloop (RIP), neuralink, his garbage LLM called grok. Even the most highlighted promise of his, electric vehicles, has been a failure in both quality and proliferation. So he has turned into a kkklansman pope hide the fact that he is a huckster.
Grok's woke!
I always wondered why Amazon picked up the show, but that'd make sense. I don't remember if immortality/an extremely long life was possible within that universe, though.
It is kinda. Saying how or why would spoil the series, it's not really a good thing though
The average human on earth in the expanse can live to a hundred and thirty quite comfortably, the rich and the martians considerably longer and in more comfort.
