New Delhi, Dec. 30 -- Bernie Sanders has been speaking out against artificial intelligence (AI) for some time now. Now, he has questioned some of the world's richest people about their high-level investments in AI.

The Vermont Senator, while speaking on CNN's State of the Union, questioned American billionaires like Elon Musk and Bill Gates over their take on AI.

Sanders quoted Musk as saying, "AI and robots will replace all jobs. Working will be optional." He then quoted Gates as saying, "Humans won't be needed for most things."

The 84-year-old independent politician then asked, "Without jobs and income, how will people feed their families, get health care, or pay the rent?"
