What happens when Bill Gates, Sheryl Sandberg and Mark Cuban grill Walt Mossberg?

On this special episode of Too Embarrassed to Ask, Kara Swisher and Lauren Goode say bon voyage to our friend and colleague Walt Mossberg, who is retiring from journalism after nearly 47 years — and they're joined by a parade of tech celebrities. Mossberg answers questions from people like investor Mark Cuban, Apple SVP Phil Schiller, Google CEO Sundar Pichai, Microsoft co-founder Bill Gates and Facebook COO Sheryl Sandberg, who finally got the chance to turn the tables on him. He also talks about what's next for tech and media, and which stories in his career he was most proud of.
