The thing is, part of the reason AI requires supervision is because it's producing human-maintainable output in languages oriented for human generation; It is my belief we're at a reality akin to the surgence of the first programming langages - a mimick that allows humans to abstract away machine details and translate high-level concepts into machine language. It is also my belief that the next step are specialized AI languages, that will remove most of the human element, as an optimization. Sure, there will always the need for meatbags, but big companies will hire tens, not thousands.
