The incident was unfortunate, and a bit embarrassing, but it also gave Advaithi and me an opportunity to talk about being vulnerable and her decision to speak publicly about battling breast cancer as a CEO. The mood in the room was warm and supportive, and our interview had more moments of levity than I\u2019d anticipated when we first sat down.\u00a0<\/p>\n Rebecca Greenfield\u2014Fortune<\/p>\n<\/figure>\n I thought about that when watching Mark Zuckerberg wince on John Collison\u2019s Cheeky Pint <\/em>podcast while awkwardly sipping a pint of Guinness. It\u2019s genuinely funny, and I\u2019ve had a similar reaction when trying the beer in Ireland. (\u201cThat\u2019s just my face,\u201d Zuckerberg replied on X after the clip went viral.)\u00a0<\/p>\n I think one of the underappreciated traits of leadership these days is a sense of humor. Richard Branson has long had it, as has Warren Buffett. Apple Executive Chairman Tim Cook often pokes fun at himself, replacing his last name with an Apple logo after President Trump called him \u201cTim Apple\u201d during a White House meeting and mocking himself for posting a blurry iPhone photo a decade ago.<\/p>\n Humor is a useful tool in any public role. ADP CEO Maria Black and I laughed onstage during the summit about what our Gen Z kids said during the recent Fortune CEO Initiative \u201cgenerations\u201d dinner. Lumen\u2019s Kate Johnson and EY\u2019s Janet Truncale joked about their first meeting at the Business Roundtable. And Marissa Mayer, the former Yahoo CEO who just launched Dazzle AI, has a wry take on some of the men now spouting doomsday rhetoric in Silicon Valley. (Check out Amanda Gerut\u2019s Fortune <\/em>coverage of my conversations with Black and Mayer.)\u00a0<\/p>\n As a student at the University of Nairobi, I had an opportunity to write speeches for Mostafa Tolba, the then-executive director of the United Nations Environment Programme (UNEP). His only instruction when writing my first speech about desertification at a conference for the homeless was to \u201cmake it funny.\u201d I worked through the night, trying to come up with jokes about climate change and the homeless. Really. Dr. Tolba laughed because they were so bad and I\u2019d clearly misconstrued his instructions. \u201cNo, Diane. Don\u2019t joke about serious subjects,\u201d he told me. \u201cJoke about me.\u201d Before we can connect to solve tough problems, he explained, we have to connect as human beings. Good advice that\u2019s stuck with me ever since.<\/p>\n Contact CEO Daily via Diane Brady at diane.brady@fortune.com<\/em><\/p>\n Supermicro hires a new CFO nearly two years after promising a replacement<\/b><\/p>\n Supermicro <\/span>named<\/span> former Western Digital finance chief Mark Long as CFO, effective immediately, nearly two years after committing to replace longtime finance chief David Weigand.

He said Chinese AI models are approaching U.S. performance despite the restrictions, though China\u2019s chip workarounds still face cost and efficiency disadvantages.<\/span><\/p>\n S&P 500<\/b> futures are up 0.19% this morning.
