It's all speculation on all sides. We may never get off out of our own solar system, because the costs involved may simply be too high. Or, we could come up with a method of FTL travel in the next 100 years. 150 years ago, who would have thought we'd be flying, much less setting foot on the moon and creating our own little miniature stars, all within the last century? Statistically speaking, it's highly likely that there is more intelligent life in the universe because, as far as we know, the universe is infinite. But we don't really even know that, so, everything is ultimately mere speculation.We have not been to a planet on foot and the prospect of that happening to a star nearby is not likely to happen within the next thousand years.
And, Orion, I'm still curious - what are these utopian societies you spoke of earlier? So far, that's been the subject in this thread that has most fascinated me.
