>Going to Mars is easy, colonizing Mars is a pipe dream.

I can't tell you how much I appreciate hearing this position from someone on this site. I've tried to make that argument here and elsewhere, and it's met with an almost religious fury. I really appreciate that I'm not alone in my intense skepticism of this "colonies on Mars: coming soon!" nonsense. I'll believe it when we've solved, or at least even begun to address the big problems involved.

The oceans are orders of magnitude more hospitable to mankind & human life than is Mars, and yet we have, to my knowledge, absolutely no undersea colonies. The idea that we'll colonise Mars before we colonise the oceans (a full three-quarters of the globe) is, simply, insane.

Supply & demand. There's just more people who want to colonize mars. if you're going to make the argument of living underwater, then you might as well live in the desert where it's probably even easier. Just because something is easier doesn't mean you should do it.

Completing the circle of comments, this is exactly what this SV adage warns against: Don't trust customers promising to buy something once it is built, because they may not.

The "demand" on Mars colonization is essentially unproven.

Perhaps the attitude of "Let's do it!" is exactly what's needed for the first step of solving big, difficult problems?
