I wonder if you went back before we had any idea how the brain worked and talked to the smartest people about how neurons work (without giving away that it's a human brain) then asked them all "would such a system be intelligent?" how many would say yes.

The main problem I have with people stating it's not intelligent or conscious is I don't think we even have a good definition of either word that satisfies everyone. Philosophers have been trying (and failing) to elegantly define these things forever and everyone out here proclaiming they've got the definitive answer and this specific thing they're seeing doesn't fit under it.
