You didn't even understand my comment. I meant it's painfully obvious to me. It should have been obvious that I didn't mean it was obvious to everyone, but obviously some people can't see the obvious.

I could write a long essay on why we're not on the verge of expanding beyond our home planet, but I feel that it would be a big waste of time. I'm not going to change your mind, you're not going to change my mind, and that's one reason why humanity is ultimately doomed.

The reason that essay would be long is because you'd have to explain away so much successes from multiple independently operating space industries.

We have a handful of humans living temporarily in Earth orbit. We have precisely zero humans living permanently off planet. That's not much progress toward a self-sustaining space colony millions of miles away in an extremely hostile environment.

We don't even know whether the human body can survive long term in the much lower gravity of Mars. Life on Earth didn't evolve for that. The whole idea could be doomed from the start.
