I tried discussing energy drinks with it and found out that the King of Sweden has just issued an edict against Red Bull.
I do love the idea, though. It it were possible to use ideal training material, it would be close to time-travel.
As it stands, there's a limit to what one can learn from the text it produces. Much value, imo, would come from what the model does not know. Ideally it would be difficult even to have it comprehend user prompts, due to how different English is today.
