About the show

A weekly conversation about AI, technology, startups, and the future from people who've actually built the systems everyone uses. Chris Slowe CTO'd Reddit through hypergrowth and its IPO. Marty Weiner was a founding engineer at Pinterest and Reddit's first CTO. Zach Weinersmith is the creator of Saturday Morning Breakfast Cereal and the NYTimes bestselling author of books exploring the future of science and technology. Each week we debate the biggest stories, explain the technology behind them, and occasionally wander into philosophy, history, and whatever weird rabbit hole AI sends us down.
