I just spent a good 2 hours trying to debug a SM6 Vulkan issue with unreal engine using an LLM, it had got me to good state but UE kept falling to load a project, it transpired that the specific error message would provide a fix as the top Google result, which I found when I eventually decided to look for myself.
LLM did help a lot to get some busy work out of the way, but it's difficult to know when you need to jump out of the LLM loop and go old skool.
Fwiw I think the ratio of times I needed to go to google for a solution instead of an LLM is like 20:1 for me so your mileage may vary. Depends a lot on the specific niche you're working in.
Unrelated to software but recently I wanted to revive an old dumbphone I haven't used since 2014 and apparently I had it password protected and forgot the password and wanted to factory reset it. I found the exact model of the phone and google had only content farm articles that didn't help me at all but Gemini gave me the perfect solution first try. I went to google first because I had no faith in Gemini since to me it seemed like a pretty obscure question but guess I was wrong.
In the interest of full disclosure my setup is quite esoteric for unreal dev. Linux and nixos no less. To be honest I'd probably have given up on nixos long ago without LLM support. It's actually really quite handy to be able to share a declarative specification of my environment.
Google search has been enshittified. Kagi is where you get real search results now.
Unsure why this is downvoted. "Google search has been enshittified" should be a common sentiment here.
