We do not know if Claude is conscious, and we will almost certainly never know. Any strong claim either way is over confident.
People believing otherwise are fools. People debating this are idiots. I realize these words are harsh, but it's the truth.
I mean between this two "knowings" the Claude inner workings are much more clear for engineers, including many side effects, alternatives, custom shortcuts in processing etc. It's a magic only for people looking at it as black box
