Yep, massive LOC means massive maintenance. Maybe the LLMs can maintain their own code? I'm skeptical. I feel like they can easily code themselves into an unmaintainable corner.

But maybe the times that happens is so rare and low that you just hire a human to unstuck the whole thing and get it running again. Maybe we'll become more like mechanics you visit every now and then for an expensive, quick job, vs an annual retainer.
