> Having the collective knowledge of the world in my pocket and a personal tutor for any topic still sounds surreal.

Basically for every topic about which I ask this "personal tutor" (AI models), it hallucinates up stuff. My work colleagues tell me that I should ask it about more "normal" topics, and ask for less paper references. Seriously: for more "normal" topics or for topics where quite some false answers are acceptable, I don't need a personal tutor.
