So far, experiments have shown that one cannot expect people to remain as diligent after extended periods of LLM use.
This is absolutely a problem if you work in a shitty sweatshop that forces you to be a sin eater for robot code.
The way we do it is, the tools are available, but you're not required to use them in any specific way or really, at all if you don't want to. You do, of course, have to get your work done and be responsible for your code. We have a spectrum of use, from all-in cascades of agents through folks who use it as little more than a search engine.
We had a few incidents where people were caught out and couldn't explain why their code did what it did, but that seemed to be enough to warn the rest; that hasn't happened in a while. I don't see our "velocity" stats, so I don't know if/to what extent the robots are speeding us up, but knowing our bean counters we wouldn't be maintaining our spend at this point if there weren't a visible bottom-line result. I do see our bug and incident metrics, which haven't seen any impact from LLM use.
If you work in a shithole, yeah, they're going to burn you out. But that's about sociopathic management, not the robot. They'd wear you down a different way if LLMs didn't exist.
