The last I saw, AI models were very good at explaining what code did at a very superficial level, but not why it's doing that or why it's written that way.

I assume it's gotten better at that since then. (?)

e.g. They'd be able to write comments for x = 0 along the lines of "set variable x to 0" but not why it's being done or even why it might be a good idea.

Deeper question: What can AIs do with obfuscated code? Can they pick that apart and explain it? What if it's regular code with misleading function names?
