Nvidia buys Arm for $40B

Nvidia, the graphics card giant, announced Sunday night an agreement to acquire the Arm Limited chip operation from SoftBank Group for about $40 billion.

Arm has designed chips used in many of the world's most popular consumer devices, but generally relies on other companies for physical fabrication. Meanwhile, Nvidia is the world leader in consumer graphics, led by the PC video game market. By melding Nvidia's graphics prowess with Arm's design expertise, the combined company could challenge both Intel and AMD in the broader chip market.

In recent years, Nvidia has expanded from the gaming market into artificial intelligence and other business applications. The potential ARM acquisition enhances Nvidia's position in mobile and industrial chip markets.

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.
