At the core of most of the electronics we use today are some very tiny, very powerful chips. Semiconductor chips. And they are mighty: they help power our phones, laptops, and cars. They enable advances in healthcare, military systems, transportation, and clean energy. And they're also critical for artificial intelligence, providing the hardware needed to train complex machine learning. On today's episode, we're bringing you two stories from our daily show The Indicator, diving into the two most important semiconductor chip companies, which have transformed the industry over the past 40 years. First, we trace NVIDIA's journey from making niche graphics cards for gaming to making the most advanced chips in the world — and briefly becoming the world's biggest company. Next, we see how the Taiwan Semiconductor Manufacturing Company's decision to manufacture chips for its competition instead of itself flipped the entire industry on its head, and moved the vast majority of the world's advanced chip production to Taiwan.

(Note: A version of this episode originally ran in 2019.) In 1794, George Washington decided to raise money for the federal government by taxing the rich. He did it by putting a tax on horse-drawn carriages. The carriage tax could be considered the first federal wealth tax of the United States. It led to a huge fight over the power to tax in the U.S. Constitution, a fight that continues today. Listen back to our 2019 episode: "Could A Wealth Tax Work?" Listen to The Indicator's 2023 episode: "Could SCOTUS outlaw wealth taxes?" This episode was hosted by Greg Rosalsky and Bryant Urstadt. It was originally produced by Nick Fountain and Liza Yeager, with help from Sarah Gonzalez. Today's update was produced by Willa Rubin and edited by Molly Messick and our executive producer, Alex Goldmark.
