Do we know that it decreased the quality, or introduced more opportunities for bugs by simply increasing the velocity? If every commit has a fixed probability of having a bug, you'll run into more bugs in a week by going faster.

That's an easy question to answer - you can look at outages per feature released.

You may be instead looking at outages per loc written.

AI is constantly trying to introduce bugs into my code. I've started disabling it when I know exactly where I'm going with the code, because the AI is often a lot more confused than I am about where the code is going.

Do we know it increased the velocity and didnt just churn more slop?

Even before AI the limiting factor on all of the teams I ever worked on was bad decisions, not how much time it took to write code. There seem to be more of those these days.
