What is the point of reducing everything to nothing, or to the same thing? I mean I get it, technically it's valid, but it's very boring, there's nothing then to talk about. We are humans and we do have subjective experiences and classify things into different groups, and trying to understand the relationships and differences between groups gives us interesting things to think and talk about.

But hey, if a rock and a computer are the same thing, and computation is meaningless, words are meaningless, etc - why have you bothered to say anything at all?
