> The right approach would be to say: I do not know. Let me discuss / research with my colleagues and get back to you.

I suppose that would be very close to "you've come to the experts for advice and I probably shouldn't be here because I'm not one of them", which nobody wants to admit.

For many, an honest look at themselves would end with "I don't contribute anything". They have the opposite of impostor syndrome - they don't belong, but they feel like they should, and AI helps them pretend.
