As it happens I know zip. I ported that to linux back in 0.95 days, I think the code was called info-zip in those days. Chatting with its predictor is a fanciful description to say the least.

I've also read the transformers paper mentioned in the tweet.

Of course an LLM is on some level similar to a compression system, and on some level it's also just high and low voltages on some integrated circuits. Saying "just" glorified compression isn't something I'll believe without good arguments, though.
