This is less like a nut that needs turned and more like getting the courts to consistently put "bad people" in jail or define "obscene". Just because it has to do with software does not mean it is a problem software can solve. Even if it is a human doing it, it still has to scale to many humans, and there are plenty of examples of things we have never manged to get right due to scale well outside of technological limitations. Even if you could, my example from the article was one human, with one example case, and as another human I didn't see it as a cut-and-dry bot. Try doing that with 20,000. It's not that it would be "costly", it's that it would be an unavoidable train wreck
