A more human approach to artificial intelligence

Where does the mind stop and the rest of the world begin? When Andy Clark, a philosopher at the University of Edinburgh, UK, asked this question in the 1990s, it was a world without deep learning or smartphones. As technology has developed, his argument that the boundary between cognition and the environment is porous has deepened. He spoke to Nature about the state of intelligence research and how a truly intelligent machine needs not only a mind, but also a body. There have been two main advances since I joined the philosophy and cognitive-science community in 1984.
