There are so many more benefits to sending humans into orbit as opposed to robots, you obviously can't even begin to comprehend the importance of us putting humans into space, and the mountain of data and EXPERIENCE they get.
You say that we don't have the technology required for people to live in space, yet we have already been doing it for forty years! What do you think the astronauts are doing right now, eh? I'll give you a hint, they're sure as hell not dead! We keep astronauts up in the ISS for months at a time, my friend. We have the capability, we simly have yet to implement it.
Ok, assuming that you are right, and that we are nowhere near being able to colonize the stars, then what do you propose we do in the meantime? It's not asif we can just sit around waiting, until one day, the President gets the call: " Mr. President, we have just discovered the last technology needed to go into space." I've got news for you, this isn't Civilization, this is real life. The astronauts test a myriad of new things every time the go up, it's not as if they just sit around on their thumbs, and the decide "well I'm gonna go take a spacewalk."
I suggest you become more educated in the fields you discuss, my friend, because making outlandinsh statements of "fact" like this only make you look like a fool.
EDIT: Crosspost with Tulkas, I echo your words on the shortsightedness disease.
