Jules Verne wrote about travel in space. At the time it was thought of as impossible, a giant stretch and not in our reach. We may have temporarily lost interest and the ability to pay for such adventures at this time, but I doubt I would exclude the entire future just because the current "generations" are too busy asking what's in it for me, to expand and see the benefit of always reaching for the impossible.
Remember the words of John F. Kennedy... "We choose to go to the moon in this decade and do the other things. Not because they are easy, but because they are hard." We don't do them now because they are hard and we are afraid of failure.
