Fundamentally different I would say. I understand enough about the brain to say that talking about any kind of machine intelligence in relation to brains, is comparing apples and oranges. Its not computing things in any way analogous to how a computer works. Why would it be?

Of course, computers might be able to imitate some things and far exceed some things that our brains do. That's different though.

I guess when we understand how the brain works, we can determine if your statements are true.

I get that you comment is tongue in cheek, but your brain doesn’t have a clock signal. Easily verifiable and we could easily detect it if it did. Thus, computers are fundamentally different than brains. Also, computers have nearly perfect recall and perform arithmetic much better than humans. So both statements of GP are true.
