Wendy NatherTheory (which is mine) (and what it is, too): Enshittification has led directly to acceptance of LLMs, because the public is already used to software that is unfit for purpose.
swope"AI search assist" also gives people a quick answer that isn't buried in ads (yet).
So enshittification of the broader web gives people an immediate reward for choosing AI, and that pushes them past their initial distrust of LLMs.
Consumer AI is just earlier on its own enshittification wave, though.
