the best we can hope for is people living in deep caves beneath Mars' surface.

Caves can indeed solve the radiation problem. But SpaceX's Mars Colony plans show the buildings on surface.

There is also the problem of Mars low gravity (about 1/3 of Earth's). On the long run, this would be very damaging.

Only a moving colony on some kind of rotating vehicle could create gravity by acceleration.

It's not impossible to create it on a cave, but the amount of energy wasted moving it continuously would be enormous.

Only a nuclear plant can create this amount of energy on Mars.

It won't be easy for a private corporation to get the necessary licenses to ship a nuclear plant. Space X might be able do it with Nasa.

Notwithstanding, how can someone create a moving colony of one million residents? Or indeed a much smaller number.

It's all the same as in the 1960s and 1970s. It's just a bunch of fanciful talk, that makes more money for the talkers.
