A Nuclear Comeback: Are New Reactors the Answer?

Nuclear energy accounts for 20% of the electricity in the United States, but remarkably, 2023 marked the commissioning of the U.S.'s first new nuclear reactor in over three decades. The past few years have been a story of changing public opinion, but equally, innovative startups crafting groundbreaking reactor designs and an ambitious announcement by the U.S. government to triple nuclear power production by 2050.

Rick Rubin: Vibe Coding is the Punk Rock of Software

In this episode a16z co-founders Marc Andreessen and Ben Horowitz sit down with legendary music producer and bestselling author Rick Rubin to explore the origin of his unexpected new creation: "The Way of Code"*Blending ancient philosophy and modern AI, The Way of Code reimagines the 3,000-year-old Tao Te Ching for the age of artificial intelligence, software, and “vibe coding.” What began as a viral tweet quickly evolved into a creative manifesto—part book, part tool, part spiritual operating system for the future. Joined by a16z General Partners Anjney Midha and Erik Torenberg, the group dives deep into: How Rick became a meme for Vibe Coding —and then quickly wrote "The Way of Code"Why AI is just another artistic toolRemix culture, creativity, and collective consciousnessWhy great founders and artists need to stay true to themselvesWith shout outs to punk rock, the collective unconscious, and Johnny Cash’s famed acoustic sessions, this conversation is a sprawling, soul-searching journey across music, philosophy, tech, and truth. We hope you enjoy this deeply personal and surprisingly practical conversation on how to live—and create—in the age of AI. The Way of Code:  https://www.thewayofcode.com/“Tools will come and tools will go.
