What I see for the near future is continued progress similar to the last century in improving people's lives all over the world, some countries doing better at it than others -- generally for internal cultural reasons.
At some point population will be stable and resource usage will become indefinitely sustainable. We are fast headed that way, and we won't even have to go into space to do it (although that would be a nice bonus).
Now all we have to do is keep the world's political leadership reasonably sane for a few more decades.
We are not improving unless you measure improvement by the size of your TV screen.
