At age 69, billionaire Microsoft co-founder Bill Gates has an impressive, if mixed, résumé. But when you ask him what his biggest regret is, it’s not buddying up with Jeffrey Epstein or microchipping the populace with the COVID-19 vaccine (kidding!). His biggest failure, he told the Times last week, is his divorce.

“That was the mistake I most regret,” he said of his split from Melinda Gates in 2021. “You would have to put that at the top of the list [of failures]. There are others but none that matter. The divorce thing was miserable for me and Melinda for at least two years.”
