Computers can't think, and that is very simple. Even if it were possible, our most advanced robots aren't smarter than a retarded cockroach.

I think the true question you should be asking is that, will computers have the capacity to think? And more importantly, will they have a concious?

I personally think that we can develope a certain sense of conciousness in a computer or robot in the future. It seems plausible, although probably unlikely for the near future.
