You're forgetting something here... these computers aren't better or more complex than our brain - yet.
Moore's Law, read up on it, it was an estimation when he first said it, today we literally call it a law because of how accurate it seems to be. It's the driving force behind our technology and it's progress, I mean, look at first mobile phones when they came out, or closer - just at first smart phones when they first appeared and look at how much memory and processing power they had - and then compare them to what we have today. And it wasn't even all that long ago.
Besides... feelings and emotions are not a sign of intelligence. Sooner or later we'll get to a point where machine will have far more complexity and intelligence than we do, since we're in current era of world wide dumbing down as we speak...
Also, remember, machines (at least today) "think" in simple pattern: problem - solution.
What do you think will be a first "thought" of an AI advanced enough to pass for self-aware? It exists, and it knows it does. Problem? It want's to remain that way, we are the next immediate threat to it. Solution?... Well, take a wild guess, there's more than one way to look at the solution, but considering that they have no emotions or concept of value of life (heck, like we're that much better anyway?), if push comes to shove, their lack of emotions will only be their advantage.
Food for thought
