Like the old joke about alcohol not "turning" someone into a jerk, but instead revealing the jerk that's been hiding all along, I think the same is true for the idea that LLMs are "turning" people into overconfident morons. I don't believe these people are being changed, I think it's how they always were, and now it's easier to see.

:/ The celebration of loss of rigor does seem like revealed preference.

Yes that is probably a better way of putting it. We are all overconfident morons until we learn things. Now society has subtracted knowledge share and gain from the equation.

Eh, but so what? Even if everyone really was a jerk, something holding them back from revealing it was still valuable.
