This hasn't been my experience. I'm finding that I'm spending less time on maintenance precisely because it's less tedious to maintain as I go now, and because the "make a small change across 400 files" type thing which would have seemed impossible before can be chewed through by an agent in a couple of hours.
Usually, that is the kind of thing that's done with search-replace tools and some manual touch at the edge cases.
But AI does indeed make it faster and easier. Why sift through the changed lines and hammer down the edge cases yourself if you can get an AI to do it?
