Well, using that analogy, I would say, it took us indeed great efforts to reach it, but now we have vast land to colonize - meaning applying all that groundbreaking research into everything. There are so many more technologies avaiable, than just what you can buy on the market.
Sci-Fi is very possible.
edit: oh and about FTL:
I know I do not really understand quantum physics and co. but I think I understand, that no one really understands it yet - so I do not expect FTL in my lifetime, but I would not rule it out.
