I love philosophy but I admit I am very out of my element here haha. Never bothered with this subject.

From my naive understanding the "mind" (which I already think is a bit of an artbitrary definition without a clear limit/definition) is composed by several elements, say X Y and Z, each one with their own sub elements. As you say unless we build an exact copy we are not gonna have all elements (or we might even have a partial element, say understanding, without all the sub elements that compose it)

I think, for example, that whatever elements compose moral relevance is obviously lacking in modern day IA. That is not controversial. So apart from this I find very uninteresting to try to figure out if a machine can "understand" exactly like a human or not.

So I think as long as we stick with a very precise language it can talk about it in a more meaningful way.
