Not a Fan of Autonomous Vehicles

If there’s one thing Arnold knows, it’s money and energy. In a recent interview on Power Lunch, the billionaire philanthropist discussed the oil market and the impact of autonomous vehicles.

“Oil is fascinating because there is this big shift, for decades the question has been about supply,” Arnold said. “The coming 10 years is more about demand.”

He also stated that electric cars, autonomous cars and ride-hailing apps could hurt the demand for oil in the future.

The “convergence of these four technologies … Those will come together to structurally change transportation in the future. So people aren’t going to own cars in the future. People are going to use transportation as a service,” he said. “The ramifications for that are terribly bearish for oil.”
