I think the flaws are going to be solved for, and if that happens, what do you think? I do believe there needs to be a human in the loop, but I don't think there needs to be humans, plural. Eventually.
I believe this is denial. The statement that the best AI can't be reliable enough to do a modest refactoring is not correct. Yes, it can. What it currently cannot do is write a full app from start to finish, but they're working on longer task execution. And this is before any of the big data centers have even been built. What happens then? You get the naysayers that say, "Well, the scaling laws don't apply," but there's a lot of people who think they do apply.
