ML is essentially fancy pattern matching roughly resembling the human visual system, which is why it happens to be good at tasks related to perception. It seems that an application like cancer diagnosis - feeding in test results and medical information to a NN, it finding patterns better than any human could, has nothing to do with human perception systems. It's just much better and faster at detecting patterns in complex things than humans are.
