Yes charlie, it's confirmed. Google, lead by Kurzweil, is actively working to hit the technological singularity.Feb 26, 2014 at 1:55 PM
I think you are confusing possibility with practicality. If "interstellar space travel" was impossible, what does that mean? That the solar system is actually in a snow globe?
"The question of whether Machines Can Think... is about as relevant as the question of whether Submarines Can Swim." --Edsger Dijkstra
In case you don't get what Dijkstra is getting at here, a whole lot of science (mathematics and computer science especially) can get easier when you avoid deriving it from what is observable.
I don't agree - there is nothing unique about human intelligence, it developed from a computation (actually a kind of genetic algorithm). In fact labeling intelligence as "human" or "artificial" is kinda pointless. If humanity through evolution gained enough intelligence to "recursively" produce its own traits, then is artificial intelligence really artificial or simply a consequence of a natural process?
