Expertise, or the feeling of it
The Dunning–Kruger effect, and the question of which direction AI actually pushes people.

Recently I was reminded of the Dunning–Kruger effect, and it made me think about the influence of AI.
Could AI push people in both directions at once? It can boost real expertise — you cover more ground, you get something to check yourself against. But it can just as easily create the illusion of expertise, where you know a little about everything and become overly confident in an understanding you never actually built.
