Bill Gates talks about why artificial intelligence is nearly here and how to solve two big problems it creates

Bill Gates is excited about the rise of artificial intelligence but acknowledged the arrival of machines with greater-than-human capabilities will create some unique challenges. After years of working on the building blocks of speech recognition and computer vision, Gates said enough progress has been made to ensure that in the next 10 years there will be robots to do tasks like driving and warehouse work as well as machines that can outpace humans in certain areas of knowledge. "The dream is finally arriving," Gates said, speaking with wife Melinda Gates on Wednesday at the Code Conference. "This is what it was all leading up to." However, as he said in an interview with Recode last year, such machine capabilities will pose two big problems.
