In another sign of how the news likes to create controversy, Stephen Hawking commented publically (in Hong Kong) that humanity's best hope for survival is space colonization (he specifically mentioned the Moon and Mars), and CNN immediately quotes back some MIT profs who say he's talking outside his area of expertise, and it'd be better to build a shelter underground, underneath Antarctica.
Ugh, the way they're trying to undermine him sickens me - the point of the statement was to say that humankind needs to band together, and even if we don't kill ourselves, the universe will so we need to do it NOW. We would be better off starting to pursue mulitple avenues than to fight over which one single way is THE right way. I admire Hawking (even more) for finally stepping forward and saying these things. It is the duty (I feel) of public figures to be role models to the rest of the people, and showing us the folly of our ways is a wonderful way to do so.
You go, Hawking!
