Do you understand the code?
What was the speed up from months to weeks? You just didn't know what to type? Or you didn't know the problem domain? Or you found it hard to 'start' and the AI writing boiler plate gave you motivation?
In my experience with AI tools, it only really helps with ideation, most things it produces need heavy tweaking - to the point that there is no time savings. It's probably a net negative because I am spending all of my time thinking how to explain things to a dumb computer, rather than thinking about how to solve the problem.
