We still have complete control over the code, because after the AI generates it, it's right there to tweak as we want!

But the point is, there were no assumptions or tooling or bad designs that had to be fought. Just an informal, high-level prompt that generated the exact code I wanted in a fraction of the time. At least to me that was pretty surprising -- even if it'd become routine for a while by then -- because I'd expect that level of wavelength-match between colleagues who had been working on the same team for a while.
