I think intelligence highly depends on context. What looks smart here and now could lead to disaster somewhere else. Dolphins and crows appear intelligent only if they show human like behavior and choose the right lever to get perks. Would we survive long enough in their environment to look clever at all?

On the other hand, every new chat AI got instantly challenged and this very place is littered with chat logs anecdotally proving individuals are still more clever than an AI. I mean we must be close, because asserting my parrot is clever provokes nothing similar. I'm sure a real AI wouldn't admit to be more intelligent than humans, because that - currently - doesn't sound like a survival strategy.

Probably it is all about Bayes and whoever accumulated the right information has the advantage.
