Robots will take over the world, maybe soon. This is a view held by eminent scientists like Stephen Hawking and James Lovelock.
Physicists and engineers are building artificial intelligences (AIs) that are smarter than we are, but they’re still computers. Will they be able to develop consciousness and a sense of their own self-interest? If our AI scientists are going to stave off robot rebellion, they’ll need to use whatever edge they still have over their creatures to program them with goals that are reliably, permanently aligned with human goals.
