Well, it would by all means be awesome if we could build an intelligent system that didn't match the one we already have. And we even have an existence proof that such a thing is possible, given enough design time. Unfortunately, the existence proof says nothing about the odds of doing so very quickly -- in less than, say, a million years, which is very quick by historical standards.
