Preface: Most of my understand of how LLMs actually work comes from 3blue1brown's videos, so I could easily be wrong here.

I mostly agree with you, especially about distrusting the self-interested hype beasts.

While I don't think the models are actually "intelligent", I also wonder if there are insights to be gained by looking at how concepts get encoded by the models. It's not really that the models will add something "new", but more that there might be connections between things that we haven't noticed, especially because academic disciplines are so insular these days.
