I used to volunteer inputting data into Cyc back in the day. And I get massive déjà vu with current LLM's. I remember that the system ended up with an obsession with HVAC systems lol.
When I got to go to Cycorp in the late 80's for training, I had some really interesting talks with the people there. They got funding from a lot of sources, and of course each source needed their own knowledge encoded. One person mentioned that they had a fairly large bit of the knowledge base filled with content about military vehicles.
