Duh, it's a ML algorithm that requires an enormous amount of feedback. It can't get smarter than humans, because then there's no one, or no data, who can tell if what it's spewing is really clever or just nonsense.
I hate what happened to common perception of "AI". The whole amazing field of machine learning has been reduced to overhyped chatbots, with so many misconceptions repeated even by experts who should know better.
