But does it qualify on the ones that matter? I genuinely don't think it matters whether a person's mind is running on fat and water or silicon and copper. What should matter is if it's a person. We need a test for it that we're willing to stick to.

Since we don't know how consciousness arises, we don't know whether the physical substrate matters. It's entirely possible that it does. We also run different algorithms and have a different connection graph.

I assume you are conscious because I am conscious and you're built the same as me. An AI is not built the same as me.
