I remember this being said as far back as 2022 yet we're still here fixing things manually when the models inevitably code themselves into a hairball convoluted enough they can't find a way out.
No one at a FAANG is fixing things manually these days.
If it turns into a hairball, just have a few agents rewrite it.
Do you have any source to back this claim? I haven't heard of any Facebook, Instagram, Google or macOS rewrites being fully done with agents.
