Speculation about this sort of thing is fun, right enough, but that's all it is. We're never, EVER going to reach extra-solar planets, we're NEVER going to colonize any place other than Luna or (a bare possibility) Mars.
At this point, the theoretical physics don't even exist for things like wormholes, warp drive, generation ships and so forth. Even if they did, can you seriously see the world's governments allocating the money and resources for the engineering to make these things practical? Try telling the billion Africans we'll have round by then that they need to get by on even fewer calories so we can build starships. Expect your engineers to be lynched and your research facilities to be reduced to rubble by angry, hungry mobs.
Earth. That's it, folks. The only planet we have, the only one we're ever going to have.
