On the one hand I'm not sure Dawkins has read/thought enough about how LLMs actually work. I'm getting the impression he doesn't fully appreciate or is somehow forgetting that it's a text completion algorithm with a vast number of parameters and that even if the patterns of learned parameter tunings are not really comprehendible, the architecture was very deliberately designed.

But on the other hand his thoughts at the end are interesting. Summary:

Maybe our "consciousness" is like an LLM's intelligence. But if not, then it raises the question of why do we even have this "extra" consciousness, since it appears that something like a humanoid LLM would be decent at surviving. His suggestions: maybe our extra thing is an evolutionary accident (and maybe there _are_ successful organisms out there with the LLM-style non-conscious intelligence), or maybe as evolved organisms it's necessary that we really feel things like pain, so that evolutionary mechanisms like pain (and desire for food, sex etc) had strong adaptive benefits.
