Indeed, I am just building apps people use, they are not "critical infrastructure" and the world won't end if there's a small bug, I don't vibe code self driving cars, defense systems or medical devices. A

If there is a bug, it will be fixed quickly anyway, so only a few users might ever see it, or see it only for a brief time.

Even when manually coding, projects still have issues and bugs, I don't think much changes in that aspect now, if anything, there are fewer bugs now in most high quality apps than before, due to AI catching more issues. See all the vulnerabilities found in old core code and libraries nowadays, that humans didn't find.
