Generation ships?. What a horrible idea! Free space, fresh air, sunshine. A home planet is where its at and Earth is as good as any. If not the only one supporting our existence.
To you, maybe!
I say we find planets that we can terraform and create new homeplanets. I'd definitely join the colonization crew of such a ship! Even if I never get to see the planet myself. The adventure, my friend, the adventure!
Or we use cryosleep, I'd also like to be part of the colonization process myself.
Besides we are alone (for now). Where would we go with a generation ship and limited fuel, food and air?
To a planet that has similar temperatures and gravity as Earth. Our telescopes have picked up a few of those, though they can't support life (at least not like ours) at the moment. That's where terraforming comes into play.
