Can you point out exactly where it says that? As I read it, the claim is that AI boosts the productivity of writing code to the point that it's usually not productive for humans to write code directly. I think that boost only goes so far -- safety-critical code still needs to be well-understood by people, and a lot of the higher level thinking has insufficient ground truth to train AIs on it -- but it's fundamentally a claim about transforming software development rather than ending it.
