How serious are Elon Musk and Mark Zuckerberg about a proposed fight inside a cage? According to UFC president Dana White, “both guys are absolutely dead serious.”
In an interview with TMZ on Thursday, White said he “probably spent an hour-and-a-half on the phone” with both of the world’s most high-profile tech billionaires and found out that neither of them was kidding about a proposed cage match stemming from a social media spat.
