I doubt robots will suddenly rise up and take over on their own accord. Just because they have intelligence doesn't mean they will have ambition or compunction to control anything. We're scared because we see ourselves in AI along with all our dickish sociopathic habits, but AI isn't quite that much like us. It'd have little reason to take over and destroy us.
Rather what I think will happen is that we will slowly throw our lives away to the machines and humans will become stupider and stupider. i.e. the real danger is ourselves.
