We have enough technology now if we wish to leave the solar system. What we don't have is a good enough reason to do so. It won't be cheap, though, even if we build our starships out of asteroid material and launch essentially nothing from the surface of earth.

Yes, we can leave the solar system. But how long would it take just to reach the closest star? I think we are going to need something that goes beyond star ships or rockets, if we ever want to consider realistic, reasonable interstellar travel. Even at the speed of light, it's too darn slow. What this may be, I haven't a clue.
