On Monday, Microsoft billionaire evil-tech-baron–turned–huggable-philanthropist Bill Gates, gave his final keynote address at this year’s Consumer Electronic Show. At some point during his remarks, he unspooled a farewell video. A humorous thing — the kind of in-house-produced clip in which colleagues and friends of the soon-to-be-retiring exec offer wry testimonials and mock-stern admonishments. And in this case, friends of Bill include: Matthew McConaughey, Jay-Z, Steven Spielberg, Bono. And other famous persons. Check it out in the clip below — the video starts about one minute in.
