The most WTF moment for me was that recent Visual Studio versions hooked up the “add missing import” quick fix suggestion to AI. The AI would spin for 5s, then delete the entire file and only leave the new import statement.

I’m sure someone on the VS team got a pat on the back for increasing AI usage but it’s infuriating that they broke a feature that worked perfectly for a decade+ without AI. Luckily there was a switch buried in settings to disable the AI integration.
