That's where experience comes in. I can check someone's work way faster than I can write it. AI's right now are like junior assistants who need to be supervised. They are wrong sometimes but they can help you as long as you know their limits.

How does someone gain experience if they are using AI from the start? They never develop the skills by putting in the reps.

I also find it much harder to go through someone else’s code than to work with my own. If I’m just glancing at it, it seems to technically work, and it needs a rubber stamp… sure, that’s easy. If it doesn’t work, especially if it’s a logic issue rather than a hard error, that takes time to read and learn the context of everything that’s going on. Will someone in school today even have the skills to do that if they only ever use AI?

Sorry guy, but I don't believe that. You can check for obvious mistakes faster. You will not see any other than obvious mistakes analyzing the code as double as long than it took to write.
