Well we do have strong AI in a form factor the size of an average human's head. And that AI, while not super human in most cases, is not specially tuned to be intelligent for the sake of intelligence. It's only as intelligent as evolution 'needed' it to be to survive. I can't prove, but I'm convinced that it is possible. You don't have to be convinced, but I hope you see why I state my case so confidently.
