It ain't "intelligence."
It's stimulus-response.
Yes. But the problem from the materialist perspective is that the human mind is also just a big dumb calculating machine engaged in stimulus-response reactions across a biological network, as opposed to an electronic network.
If consciousness is simply an "emergent property" of sufficiently complex calculating systems -- whatever that is supposed to mean -- the issue is not that some mystical quality has been assigned to sophisticated AI "thinking."
The issue is that that the materialists deny that human thinking is different in kind. On materialist grounds, what is the difference between the consciousness of an electronic computer as opposed to a biological computer operating on a neural network? It's not clear that there is any. Complexity and processing speeds are the thing, and it seems likely that the AI version will eventually be bigger, more complex, faster and more powerful.
