It also isn’t really clear to me that humans aren’t also interpolating between complex existing concepts when we come up with novel thoughts or ideas. Our minds are complex, our pre-existing knowledge base is complex. It’s impossible to know if our unique thoughts aren’t really some complex amalgamation of other thoughts we already have in there somewhere, perhaps a mashup of seemingly unrelated thoughts that just happen to lie closely in the multidimensional space of ideas to the thing we are thinking about. Sounds potentially similar to a complex LLM then, really.
