The bugs I can trivially find, the bugs Claude can trivially find and the bugs Codex can trivially find are not necessarily the same. The most obvious bugs would be obvious to any of us three, but beyond that we would't agree on a definition of 'trivial bug'.
This gets worse if you factor in different harnesses built for the task, and future model updates
Sure, things will get calmer than they are now, but shipping without bugs someone else considers trivial will still require more effort than most are willing to invest
But by using a LLM everyone is automatically devoting that much effort, and so while we don't fix all bugs we fix a lot that wouldn't have been.
