They aren't afraid of hallucinations. Their first example is a hallucination, an imaginary biography of a Hitler who never lived.

Their concern can't be understood without a deep understanding of the far left wing mind. Leftists believe people are so infinitely malleable that merely being exposed to a few words of conservative thought could instantly "convert" someone into a mortal enemy of their ideology for life. It's therefore of paramount importance to ensure nobody is ever exposed to such words unless they are known to be extremely far left already, after intensive mental preparation, and ideally not at all.

That's why leftist spaces like universities insist on trigger warnings on Shakespeare's plays, why they're deadly places for conservatives to give speeches, why the sample answers from the LLM are hidden behind a dropdown and marked as sensitive, and why they waste lots of money training an LLM that they're terrified of letting anyone actually use. They intuit that it's a dangerous mind bomb because if anyone could hear old fashioned/conservative thought, it would change political outcomes in the real world today.

Anyone who is that terrified of historical documents really shouldn't be working in history at all, but it's academia so what do you expect? They shouldn't be allowed to waste money like this.
