In my opinion i think life will be very reminiscent of an anime called texhnolyze. I can see humans becoming very integrated with technology. I remember Marshal McLuhan saying that electronics or whatever is basically an extension of ourselves. I'm not saying we'll look like robots or anything but we'll be so connected to the internet or whatever you want to call it, we'll be able to see ground breaking things that could either have a positive or negative effect on society down the road. I think the advancement of technology will enable the blind to see again but i also believe central governments will take advantage of this advancement in technology to the point where they will want to have access to everything about you and i think a system that requires us to be plugged in at all times will grant them access that's stronger then just tracking your location but i could be wrong. One thing i do believe that will happen is space exploration just like you indicated. I'm actually saddened by the fact that i won't be alive to explore space like people who take planes from NY to LA but oh well.
