Space travel is largely impractical with current tech. There are technologies which would make space travel practical. So humans will stay on earth and research until we find those technologies.
Suppose that sooner or later we get supersmart AI. The AI will spread out at near light speed. whether or not we have a fledgling Mars colony by this point is largely irrelevant.
