I spend a lot of time thinking about the future. When I’m deciding which book to read next, I often reach for ones that offer another perspective on where society is headed next. So when Satya Nadella—whom I knew for 20 years before he became the CEO of Microsoft-- told me that he was working on a new book about the future of technology, I couldn’t wait to read it. I think you’ll enjoy “Hit Refresh” as much as I did.
