One cool aspect of LLMs is Vernon Vinge's programming archaeology needn't be a thing... LLMs can go down every code path and identify what it does, when it was added, and whether it's still needed.
You think even ten years from now, much less 1,000 years from now, whatever LLMs turn into won’t be at least as capable as the best human of following code paths?
We can spin up a million of them and run them at 10,000x speed.
