One huge issue is that LLMs do weird and stupid things differently than how humans do them.
If you've developed an eye for reading human-made changes, you're not necessarily going to recognize new and surprising failure modes as easily. It's literally harder than regular code review.
Humans with modern tooling, for example, rarely hallucinate field/class/method/object names because non-spicy autocomplete keeps them on the rails. LLMs seem much more willing to decide the menu bar is .menuBar and not .topMenu, probably because their training corpus is full of the former.
Then maybe the West shouldn't have spent 50 years selling the PRC the rope they're using to hang them with.
Even some of the near east is starting to think about what happens when the goo runs out. Only the US is doubking down.
