> "A computer" in the first statement is IMO obviously intended in the common usage sense of the term, i.e. the brain is not a desktop computer
replyNo one has ever thought that a brain is a desktop computer, and that is not the common usage sense of the term in this context.
You are wrong, as I didn't limit the analogy specifically to desktop computers only, try reading the rest of what I wrote. The original analogy was obviously hedging against simplistic brain-computer analogies (GP could be read as: "the brain is not a simplistic computer"), so the response demanding to "live with that" citing computational aspects of the brain was misguided and arrogantly wrong.
replyMultiple other responses also point out the definition given leads to absurdities / triviality (the liver is a computer in this context), so the "correction" with citations is both inept and inapt.
