Yeah, that's kind of my least favorite part about the existence of LLMs. Before, when someone wrote some code, there was a non-zero chance that they understood what they were doing and that the code is at least sane on a basic level. If they did some complex shit or even just wrote rather verbose code, you could be reasonably certain that they tried something simpler first.

Now, all of those assumptions are out the window. The biggest dumbass can generate code that looks alright at first glance and if you have to review it, you really don't know how to interpret it or how much to explain when you find fairly obvious mistakes.
