Elon Musk was in an online argument this week, which is not new but this time, it wasn't with a rival CEO or a world leader, but with the website Chess.com.
On Thursday, Musk wrote that the number of chess moves that aren't "utterly stupid" is small and that "chess will be fully solved one day."
Chess.com's official account responded by calling the prediction a "skill issue." Musk replied that chess was hard for humans but not for computers.
