"Supervised" does not mean the models need babysitting; it refers to the fundamental way the systems learn. Our most successful machine learning models all require some answers to be provided to them in order to infer the rules. Without being given explicit feedback they can't learn anything at all.

Humans also do best with supervised learning. This is why we have schools. But humans are capable of unsupervised learning and use it all the time. A human can learn patterns even in completely unstructured information. A human is also able to create their own feedback by testing their beliefs against the world.
