Also, we don’t know how many billions of dollars was spent on making it work. They are running 1000s of agents against their codebase 24/7, and still only producing what they’ve put out so far.
It might be fully automated and eventually the agents figure out all of the bugs, but I suspect the costs are so large that no sane company would ever write code this way, and probably WAAAY more expensive than just hiring humans to write and test it.
