The only intelligence with human capabilities is, so far, human intelligence. We can see how nature incrementally improved 'the algorithm' when we look at other animals, from simpler ones to primates. We don't see the capabilities of even lower animals in modern deep learning based networks. We know these networks don't match in neural function what we see in biology. Whether deep learning will lead to the North Star of human intelligence is guesswork, and guesswork rarely works well with complex systems.
