>Mars will never be terraformed and terraforming Mars is a terrible idea.

isn't musk selling this idea? colony with MILLIONS of people?

he isn't the only one, MarsOne comes to mind among many others.

I totally agree with what you say, having small bases like in the artic, or simple mining colonies is feasable and interesting, but the talk here is fully functional independent colonies. that's not gonna happen anytime soon (200++ years).
