The smartest AI is dumb without people

It's easy to see the latest algorithms write a story or create an image from text and think that they are ready to take on a whole range of human tasks. But experts insist that AI systems' growing power makes it more important than ever to keep humans in the loop. Why it matters: AI-based computer systems are being used to handle an array of increasingly consequential tasks. While machine learning-trained systems do many things well, they can also be confidently wrong -- a dangerous combination. Liang has launched a project to evaluate the latest machine learning models on a range of factors, from accuracy to transparency.
