Eventually, we are going have to go into space. There are plenty of movies, books, games, ideas and other things that have all the bases covered. You can go see Aliens, Star Wars, Star Trek, Firefly and Riddick to see what our future looks like.
Now, I am hoping that it will be rather like Star Trek (with universal "peace" and understanding and that whole pursuit of personal wealth becoming a pursuit of better intellectual understanding of the universe), but knowing the human race, it will be more like Firefly or Star Wars (where one faction holds the powers and grinds the guy/girl who just wants to live comfortably into the dirt). We humans love our conflicts.
Back when JFK said those immortal words, there was a race going to beat the other guys (I'm not gonna name them but you know who I mean). That's the whole reason we eventually got to the moon. Not because we wanted to go there, but because one faction wanted to go there before the other one.
Don't get me wrong. I'm all for the exploration and exploitation of space (hoping we can learn from our previous mistakes). I'm all for of having giant solar panels in space collection all the energy we'll ever need. If it was possible to permanently live in space, I'd be one of the first to sign up. And if we ever get to see aliens, let's remember what happened when some dude decided to sail west and discover a new world. Or if that's too vague for you go watch Avatar. Or Planet 51.
There are only 2 (maybe 3) countries who in my mind have both the cash and the minds available to pull it off effectively.
But with the state of the economy as it is today, projects like fundamental research and cash-guzzlers like space exploration won't get to see the light of day.
Still, I can't wait to board my spaceship and go all Elite (No? don't get it? How about Freelancer? ... Fine ...) or Firefly all over the universe out there.
