CES 2018: Can AI deliver for humans?

In Las Vegas this week you can learn a lot about the exciting potential of artificial intelligence. You can also be left wondering whether AI is a triumph of marketing, yet to deliver real improvements to the economy and the way we live. One of my first stops here was at a University of Las Vegas robotics lab. Sophia is a humanoid robot with a face that strays dangerously close to that "Uncanny Valley" where machines look just a little too human for comfort. She achieved fame and some notoriety when Saudi Arabia named her its first robot citizen, a stunt which saw many question whether machines were now being given freedoms denied to Saudi women.
