How Rouzbeh Invented the Cable Modem

Welcome to episode #1005 of Thinking With Mitch Joel (formerly Six Pixels of Separation).

Every major leap in human connection starts as a simple question: what if? For Rouzbeh Yassini-Fard, that question led to the invention of the cable modem and the birth of broadband internet access as we know it. Often called the "father of the cable modem," Rouzbeh is a visionary engineer and entrepreneur whose work transformed how billions of people access information. His new book, The Accidental Network, traces the improbable journey from an idea nobody believed in ("why would anyone want the internet at home?") to the global infrastructure that now powers our economy, culture and daily life. In this conversation, he reflects on the messy, human side of innovation: the skeptics who dismissed broadband, the long nights building hardware that few thought possible, and the radical choice to make his breakthrough technology open-standard so the world could share it. Rouzbeh speaks with humility about how chance, persistence and purpose collided to shape the digital age, and how broadband became not just a business revolution but a social one, connecting homes, hospitals, schools and communities. He also wrestles with the moral dimension of progress, calling for a balance between capitalism and conscience as we enter an era defined by AI, environmental strain and "data as the new oil." From the early chaos of coaxial cables to the moral complexity of modern networks, Rouzbeh's story is a reminder that technology's true purpose isn't speed or profit... it's improving the quality of life for everyone it touches.
