AI sometimes points out hygiene issues that may be swept under the carpet but once pointed out can't be ignored anymore. I know I don't need that error handling, I'm certain for the near future but maybe it is needed... Also the code produced by the AI has some impedance match with my natural code. Then one needs to figure out whether that is due to moving best practices, until now ignored best practices or the AI being overwhelmed with code from beginners. This all takes time - some of it is transient, some of it is actually improving things and some of it is waste. The jury is still out there.
