> a million people on mars definitely won't be achieved this century, as the place is fucking awful

Mars could make for an interesting prison, though. Like the Australia of two centuries ago. If nobody volunteers to live there I wouldn't put it past Musk to meet his target that way.

People already lived in Australia before Britain shipped its prisoners there. It was habitable.

Nobody is spending trillions to build a prison on another planet.
