You also can't trust AI when it comes to n-categories!
In reality a 1-category is a category, a 0-category is a set, and James Dolan discovered that a (-1)-category is a truth value and a (-2)-category is a true truth value (of which there is only one: "true").
But my friend Allen Knutson asked Gemini and got this garbage. Clearly it's Russian propaganda.
