I can say that in my experience AI is very good at early codebases and refactoring tasks that come with that.

But for very large stable codebases it is a mixed bag of results. Their selection of candidates is valid but it probably illustrates a worst case scenario for time based measurement.

If an AI code editor cannot make more changes quicker than a dev or cannot provide relevant suggestions quick enough/without being distracting then you lose time.
