I predict the opposite: Humans will collectively create something like an LLM, but curated. That will be next level for Wikipedia-like project.
Think about it - LLM is just a computer program that predicts a next word. So it has a very detailed, formal description of each concept it can represent in its residual vector.
I think humans will understand (perhaps with AI help) these formal descriptions and put them into a giant database.
You say, building ontologies with a specific intent will actually lead to intelligence at a similar level of current AI?
This would be a severe blow to the bitter lesson, and generally vindicate the AI researchers of the 80s that put a bet on symbolic processing
