Elon Musk says Mark Zuckerberg's understanding of AI threat is 'limited'

The Facebook chief executive and social media icon is frequently lauded for his critical thinking and global vision, qualities that have helped him maintain his reign atop one of the world's most successful companies. Yet on Tuesday, Tesla chief executive and fellow billionaire Elon Musk said in a tweet that Zuckerberg's understanding of the threat posted by artificial intelligence "is limited." Musk's tweet was a response to a Facebook live broadcast that Zuckerberg did during a backyard grilling session Sunday in which he was asked about Musk's strident warnings surrounding AI. Musk wrote, "I've talked to Mark about this. His understanding of the subject is limited."
