The project was said to start around 2015, by then, the world would probably have had a few wars. I think things will be calmed down by then, and it would be more like the 90s. Even if it dosn't start till 15, then it'll take years to finish, not only would you have to be a space astranaught to do the mission but you'd have to have assembly skills as well.
I don't think its a bad idea at all at 2015, for all we know we could be making money by then instead of losing it.
Space IS the final frontier, it is the last thing for us to explore, everything on Earth had been seen. Humans long for new destinations and the big question- Is anyone out there? Which I believe that there is, but you never know.
