No, the claim is just that it’s harder to read and verify existing code than to write new code. Depending on the level of certainty you want, verifying code is much more expensive than writing code, which is why there are so many bugs and why PR review is, imo, practically worthless.

Switching the job of programming from designing and writing code to reading and verifying code isn’t a good trade-off in terms of making programming easier. And my first speei node with AI tools has done nothing to change my mind on this point.
