Earlier quoted context omitted.
There are strong indications that brains are prediction engines. Tokens are an implementation detail of LLMs and irrelevant to the discussion.
So we know that implementation doesn't matter as long as it is somehow making predictions (and predictions also on different things)? Most living things are prediction engines in a way, why compare to the brain then to start with and not, e.g., bacteria?
And why compare to the brain? Mostly because of complexity. I can't interface with a bacteria in any meaningful way, but I can interface with an LLM to a significant degree.
