For me the main thing is Windows has gotten so bad that I was finally willing to spend time getting Linux running. LLMs are nice, but not necessary. Claude helped me with a driver issue at least knowing where to look but the answer was ultimately on a Linux forum. I think LLMs help but it isn't that much better than just searching old forum posts.

At least for me, the availability of LLM help had nothing to do with my decision to switch to Linux, it was Proton making it to where games run great on Linux and Windows being intolerably bad.
