Kevin Mayer is out as TikTok's CEO

After only three months at the company, in a job with very different responsibilities than he expected (and a title that may not exist for long), Mayer reportedly told his team he's leaving.



In an email to staff, he wrote that "In recent weeks, as the political environment has sharply changed, I have done significant reflection on what the corporate structural changes will require, and what it means for the global role I signed up for. Against this backdrop, and as we expect to reach a resolution very soon, it is with a heavy heart that I wanted to let you all know that I have decided to leave the company."

Vanessa Pappas, who had previously been the general manager of TikTok and the head of its U.S. operations, is the company's new interim head.

Martin Cooper helped invent one of the most consequential and successful products in history: the cell phone. And almost five decades after he made the first public cell phone call, on a 2-pound brick of a device called the DynaTAC, he's written a book about his career called "Cutting the Cord: The Cell Phone Has Transformed Humanity." In it he tells the story of the cell phone's invention, and looks at how it has changed the world and will continue to do so.

Cooper came on the Source Code Podcast to talk about his time at Motorola, the process of designing the first-ever cell phone, whether today's tech giants are monopolies and why he's bullish on the future of AI.
