It seems like every couple of years Hawkins says this: http://bigthink.com/ideas/21570
I realize Hawkins is a smart guy, but I've done a good deal of reading on this subject and they usually require technology like Hyper Drives, Terraforming, antimatter energy generation, and self-aware robotics. In other words, stuff that'd be halfway up the tech tree of a sci-fi strategy game. It's pretty clear it requires technology we're nowhere close to achieving since if we're close to any of these technology we could use them at home too (for example, Terraforming Earth would be a lot easier than Terraforming Mars). The most inhospitable location on Earth is still way better than anywhere outside of Earth (at least we get oxygen, sunlight, radiation shielding, and probably water) but you don't see people throwing money at colonizing Antarctica or the Sahara Desert, and yet we try to colonize the moon or Mars? Sure space sounds more glamorous but I bet if you tried to colonize Antarctica you'd find that it's pretty tough even if you throw money at it, and yet it's way easier than colonizing Mars.
