How is AI ANY different than access to a super smart human? Why do we hold AI to a higher standard than the smartest humans in the world?

For one, smart people generally are conscious of the limits of their information and training.

There are those who aren't, or don't care. At Caltech we called such Nobel Prize winners, 21-year old Ph.D.s(*), and such amongst us "assholes". In my standards group, we eventually removed one of them from interacting directly with the group since his reaction to disagreement or pushback was to directly and literally accuse those people of being "idiots". Very smart in limited domains, yes. Recognized no limits, yes. Uninterested in how to interact with other people, yes.

(*) Stephen Wolfram. I was personally witness to a conversation he had with other grad students in which he called all Caltech undergraduate students "idiots". AFAICT the extreme arrogance did not appear to improve with age.

(apparently "idiot" is a go-to label amongst very smart, very arrogant people judging by my small sample size.)
