Great and thought provoking post.

It seems to me that a near perfect symbol predictor, one trained to the
point where it knew almost everything and could predict almost anything
with near flawless error rate, would be able to suffer, or at least, it
would need to invoke a suffering mind to work as flawlessly as it does.

For example, if you asked this perfect symbol predictor: "What would
Einstein say if his wife told him she wanted a divorce?" Then this perfect
symbol predictor, (in order to achieve perfect accuracy), would have to
invoke an accurate simulation of Einstein's brain, and his resulting
emotional state, shock, surprise, hurt, etc. from hearing these words, just
to determine how he would reply.

The ability of existing GPTs to build and run simple models, though
nascent, is already present. There may be millions of different possible
models available to GPT-4 which it calls upon to answer queries. Can any of
these models suffer? It's hard to say, but I can say with some confidence
that a sufficiently powerful symbol predictor would necessarily invoke
models which are conscious and some of this could suffer.
