Artificial Intelligence is helping Silicon Valley reinvent itself

For more than 10 years, Silicon Valley's technology investors and entrepreneurs obsessed over social media and mobile apps that helped people do things like find new friends, fetch a ride home or crowdsource a review of a product or a movie. Now it's found its next shiny new thing. And it does not have a "Like" button. The new era in Silicon Valley centres on artificial intelligence and robots, a transformation many believe will have a payoff on the scale of the personal computing industry or the commercial internet. Computers have begun to speak, listen and see, as well as sprout legs, wings and wheels to move unfettered in the world.
