Remember the vacuum tube train? The car tunnels? The brain implant chip? The humanoid robots? Making government “efficient”? An AGI based on… tweets (wtf)?

But sure, colonizing Mars is totally real.

@thomasfuchs He might be able to get a few people to Mars, maybe without killing anyone, maybe not. But keeping people alive on another planet for a long time is a huge challenge. (Food, shelter, oxygen, reduced gravity among other challenges)
Why?
Because I seriously doubt he’d be able to bring anyone back home to Earth successfully.
Or maybe it’s not even in his plans.
It’s a one way ticket.
Got a hotel reservation when you get there?

@bouriquet
And the massive societal restrictions it would require, especially early on. Absolutely no weapons, rationed food, rationed water, rationed *air*...
And no dissent permitted. Because it's a huge safety problem.

@thomasfuchs

@SoftwareTheron @thomasfuchs Not much different than an Antarctic expedition really. Except they get to go home and a rescue extraction is possible and can occur in short order.
The psychological challenges for Mars are huge and might dictate unique selection evaluation.

@bouriquet
There's another thing I forgot:
There is absolutely zero possibility of rescue or of replacing broken equipment. Because the mission *flight* time is 18 months or so.
That massively increases the mass requirement and the skills requirement.
