CMV: Humans will never be able to visit other planets

The technology to get us to other planets is so far out, if we ever gain it, we are no longer humans - just intelligent machinery. The size of the universe is so massive that it will never be feasible to travel to other planets. If anything, we will probably find other ways to live (e.g. Mars, moon, or space stations) but we will never be able to visit other galaxies or planets in the way we currently travel places here on earth, like flights, trains, or cars.
