I don't doubt it's normalized in big companies. I imagine the bigger the company, the more ai they use. Big companies have the most to gain from the reduced-workforce ai sales pitch, and the biggest (meta, google, microsoft, etc) need a return on their ai investment (I've yet to hear of any demonstrable roi).
It makes sense that anyone in those companies would see it as normal, but it strikes me as an observer bias or frequency illusion. There's so much ai hype. That is, after all, where the ad money and investments are flowing, but I also see a ton of skepticism, fatigue, and general disenchantment with it, which aligns with my experiences: that it doesn't compare to a good system of books, notes, and bookmarks-- and that's not even considering the costs (monetary, environmental, social, and political) which seem completely oversized. So that's why I remain skeptical of the claim that normal people use ai.
