How to train your robots: Elon Musk's new AI gym

There's a new high-tech gym in the works, but it has nothing to do with toning muscles. Elon Musk, the tech-loving chief executive of both Tesla and SpaceX, is building an open-source "gym" for computer programmers to train their robots, Sharon Gaudin reported for ComputerWorld. Developers can share their findings on artificial intelligence (AI) systems as they work out. "Nothing beats a competitive environment to motivate developers," said Patrick Moorhead, an analyst at Moor Insights & Strategy, to ComputerWorld. Championing AI marks part of a calculated strategy by Mr. Musk, who has said AI could represent humanity's "biggest existential threat" because it could prove destructive in the wrong hands or simply go astray on its own.
