> It takes longer to read code than to write code if you're trying to get the same level of understanding. You're gaining time by building up an understanding deficit. That works for a while, but at some point you have to go burn the time to understand it.

This is true whether an AI wrote the code or a co-worker, except the AI is always on hand to answer detailed questions about the code, do detailed analysis, and run extensive tests to validate assumptions.

It is very rarely productive any more to dig into low level code manually.
