Mr. Musk, in a black T-shirt and moto jacket, weighed in on the subject of the future, too.

“I think we’re currently teaching kids in school to hate America or to question whether America is good,” Mr. Musk said, reflecting on something he feels society is doing right now that will negatively affect the years to come.

“There’s a lot of focus on all things America does wrong, but not enough on what America has done, both currently and historically,” he continued. “Which then causes people to lose faith in America. And then, I don’t know, we might fracture as a society and no longer be the United States of America.”
