A few weeks ago, I saw a tweet that said “Writing code isn’t the problem. Until AI systems can generate code as reliably as our current generation of compilers, humans will need to understand—and debug—the code they write. So if you’re as clever as you can be when you write it, how will you ever debug it?”

We quickly run into an extension of Kernighan’s Law : debugging is twice as hard as writing code. So if you write code that’s at the limits of your understanding, you’re not smart enough to debug it. Humans have to test and debug code that they didn’t write all the time; that’s called “maintaining legacy code.” Language nothing.
