Elon Musk decided to create the Cybertruck because he thought Ford's trucks were 'boring,' biographer says

• Elon Musk decided to green light the Cybertruck because Ford trucks were "boring," Walter Isaacson said.

• The biographer said Musk came up with the idea six years ago and was inspired by science fiction.

• Musk tweeted on Monday that Ford's new EV truck was a "good vehicle, just somewhat expensive."

Elon Musk apparently isn't a fan of Ford's traditional pickup trucks and his distaste for the vehicles spawned the Cybertruck, according to the billionaire's biographer, Walter Isaacson.

The author, who has been shadowing Musk for about three years, said during an interview with CNBC's Squawk Box that the Tesla CEO came up with the idea for the futuristic electric pickup truck about six years ago.

"He's sitting there with his design chief Franz von Holzhausen and looking at a Ford truck and he said, 'No, these things are boring,'" Isaacson said regarding the exchange, which he said will be fully detailed in his upcoming book.

"He doesn't like to be bored and he puts up things from movies, from sci-fi, from video games and says, 'I want it like that,'" Isaacson added. "And everybody's pushing back on him at this meeting. He finally says, 'Yeah, stop it. We're gonna do it. We're gonna make it edgy.'"

On Twitter, Isaacson later shared a photo of Musk and the Tesla design chief in front of a series of pictures of what appear to be early design ideas for the Cybertruck. The biographer shared a quote from his book in the tweet, saying that Musk issued an edict in 2017 that the pickup truck would be entirely stainless steel.

"The use of stainless steel opened up new possibilities for the look of the truck," Isaacson writes. "Instead of using stamping machines that would sculpt carbon fiber into body panels with subtle curves and shapes, stainless steel would favor straight planes and sharp angles. That allowed— and in some ways forced— the design team to explore ideas that were more futuristic, edgier, even jarring."
