I don't think AI could generate 90% or even 40% of my code, but by god does it generate me a lot of boilerplate and comments. My work just gave us all Copilot and it's really good at creating useful comments (even for Pydocs), and writing out simple but mildly tedious things like the outline of a loop, simple functions etc. No risk really from either since they're all short enough for me to sanity check as the AI is writing them, but a very very useful little time saver IMO.
