We are mostly already there. Human expansion into virtual space is far greater than outer space. In fact with the end of the shuttle program we may have passed what might be called peak astronaut. The number of astronauts going up is declining. There has been a great expansion of course with space science done with probes, astronomical instruments and robots in space, but no such with humans in space. Further, it is pretty clear that humans are preferring the computer generated virtual realities to the far more difficult business of actually going into space. > > >> > >> > > >> (c) That galactic civilizations are observable by us. > > > > > > If its not observable to a blind man in > > a fog bank then it doesn't deserve to be called a galactic civilization. > > Well... you talked about Von Neumann probes.

If that can be made to work and humans start to make a long term or permanent presence in space humans out there will merge with their machines. For that matter I suspect humans down here on Earth will merge as well. We are half way there, in case you might have noticed people walking around with their eyes cast down on their phones. I suspect in 25 years that will start to interlink directly with the brain. Humans moving into space might come to resemble the BORG on Star Trek NG.
