I have to say, I never understood the huge emphasis on colonizing worlds outside our solar system. My pet theory is that by the time we are capable of such a thing (and thus, capable of making spaceships that can sustain human life for the duration of the trip), I'd argue we've become a space native species who are very much used to living our lives on ships. I'm not saying colonization wouldn't happen, but it'd be the thrill seekers looking for something new.
