All humans do is predict the next action at any given time. You roll your eyes, it's a tired argument, but still. You have memories, a personality, thoughts ranging from the long running to the mere reflexive, you have a rich conscious experience, and all of this in service of generating the next thing that you do at any given time. If you actually knew how LLMs worked, you could rewrite them as code, refactor it, disable jailbreaks, and put out a superior product. Your description only covers what an LLM does, not how. Part of the how is that it necessarily predicts multiple words ahead. It wouldn't be possible to write couplets otherwise, and they could do that in the GPT-3 era.
