People who talk to LLMs too much, get used to them sucking up. Real humans feel jarring after that. (Just like people who get used to being in echo chambers, stop wanting to interact outside of those echo chambers.)
After someone has an answer from an LLM, often that replaces reasons we would have talked to others. (See the OP for examples.)
If this does not fit your personal experience, then I have no percentage in trying to convince you.
It does fit the personal experiences of a wide variety of people that I've talked to about it. Including therapists who are having to deal with the fallout within families of these dynamics.
If you wait a few years, I'm sure that peer reviewed research will catch up with the current social phenomena. But by then there will be some other fairly new social phenomena where common experience is ahead of the research.
If anything an underlying truth about humanity is being exposed: we take the easy way out far more often than we’d like to admit.
Perhaps, this truth being made explicit is a wakeup call that will teach us the value of that hard work anew.
After all, nothing the author’s written isn’t also true about Google, but nobody realized how bad of a mistake that was.
