Tesla and Elon Musk’s Dancing Robot Bordered on Self-Parody

Today’s top tech news:

At Tesla Inc.’s artificial intelligence showcase last week, Elon Musk brought up some top engineers, who spent 78 minutes intricately detailing how their self-driving vehicle technology calculates road-surface geometry, predicts object movements, identifies traffic signs and barriers and will harness all that data to train its autonomous system with the help of proprietary chips. Then Musk welcomed a performer onstage dressed like a robot, who bounced and shimmied to electronic dance music.
