The point is that even if all code commits are scanned as safe by ai, black hats can still analyse the commits and diffs to find vulnerabilites for people who havent patched yet.
Scanning every commit doesnt automatically make everyone in the world patch immediately, vulns can still be found from commits and diffs and used against those who havent patched yet.
Look at GP to my comment again, the one I was clarifying: they're not talking about black hats or any other kind of hacker, they're talking about the original developers and preventing such vulnerabilities from existing in the first place.
Yes I am aware, however that still does not stop anybody examining your commits and diffs to find vulnerabilities.
Do you assume ai will just stop at a certain level? Or is it possible that it will keep increasing in intelligence? If the latter, then isnt it possible that even if you are auto checking all your commits, next week a more advanced ai model might be released that finds vulns in your old commits, even though they were checked by (an inferior) ai?
Blinding saying that auto checking commits will make you safe from ai based attacks and vulnerability free is just madness.
