It feels like a vanity and an anachronism to an era from the past. Manned space travel is risky, expensive, environmentally destructive, and for what? For some human being to manually manipulate scientific instruments in orbit that should have been, or could have been automated and get the same results?
Gone are the days where people actually think we could be living in space. From what we know now, not only is it impractical, dangerous, inefficient, its also unhealthy. This isn't a question of some new technology that needs created to support it, it's a limitation of physics and millions of years of evolution on earth.
Send satellites to orbit? Yes. Collect power from space? Yes. Conduct scientific research? Okay. But we don't need to send people to do that anymore. Manned space travel had its place in time, and it no longer makes sense to do it, so lets have the maturity to move on from the past.
