Personnally, a lot of bash, C, AWK at the moment (typescript + html/css until last april, now i'm back to the basics). The figure i gave in my post were more for that.
The last time i used it was yesterday, i wanted to hack something on an old game i used steam+proton for. I knew it was a weird Wineprefix, so i asked ChatGPT for it, i might have asked poorly, but after fiddling, i had the response (tbh i had to look how to get the game ID, so in the end i lost more time than not), then when it still didn't work, cause the path was shit, i entered all necessary context in ChaGPT4, and it couldn't find the easy "USER=steamuser" env variable to add before launching Wine. I stopped after 10 minutes, looked into a example Wine cfg file, understood the issue and fixed the problem myself.
I mean, it's probably good for really basic stuff, so it could have helped me when i was starting, but 80% of the stuff i code automatically without really thinking about it, and when i have to stop to think, ChatGPT isn't helping. Also tbh, VSCode is really, really good and fix my old, time-consuming task of "what's this argument again?"
Still, it's way better and more efficient than Google. Less than not being lazy and using my two braincells tbh.
