It’ll do things like write a great helper function that it uses once but never again, maybe even writing a second copy of it the next time it would use it.

Holy shit! That exactly explains why I’ve seen so many duplicated functions lately. I brought it up to the dev responsible the first time I found one (git blame), and he was just like “oh haha I can remove one” like he wasn’t quite sure what I was talking about, now I realize he must’ve gotten on that AI train much earlier than I thought…

I just switched to Librewolf from Firefox, would you recommend moving to Waterfox instead ?

I would second this heh - buy second hand, and especially if you don’t want/need anything fancy.

I recently was gifted a 2nd-hand garmin forerunner 235. Battery life could be better, but it does most things well (simple). I wasn’t sure I wanted a smart watch, but it’s growing on me.
