Again, grand claims with zero substance. What are these supposed "massive problems"? I think your definition of "massive" and mine could be entirely different things.
If it works for you, that's great, but I wouldn't trust it with anything important. It would still require a lot of my time to vet the fixes it produces, and from what I've seen (mostly from Copilot) it almost never produces an acceptable result - but then I'm probably outside the typical use case for coding AI.
My company pays for AI but from what I've seen of it, I'd never pay for it for my personal projects.
