it's hard to gauge this take without specifics. My experience with LLMs tends to be towards the opposite concept; LLMs dissuading me of hunches and notions I have about things (where I have no particular expertise; societal-level things), saving me and others time and strife having an argument about something they were actually right about all along, as my internal doubts that I'm too embarrassed to bring up (because these things aren't my field) are confirmed as incorrect.
I'd be curious to know specific examples of LLM-generated advice that goes against the advice of experts and does not consider tradeoffs. I've not had this experience myself.
If I did have this experience, someone spouting off obvious LLM points that contradict my expert opinion on something, I'd be headed right over to gemini/claude/whatever to see where that's coming from. Not any differently than if someone cited a google result that contradicted my own experience.
