About this episode
Welcome to Stewart Squared podcast with the two Stewart Alsops. In this episode, we explore the evolution of networking—from the early days of isolated personal computers to the transformative rise of local and wide area networks, and the eventual dominance of the internet. The discussion covers key milestones like Bob Metcalf’s invention of Ethernet, the emergence of TCP/IP protocols, and the pivotal role of the commercial internet in the 1990s. We also connect the dots between historical shifts in media technology, the current AI hype cycle, and predictions for the “third convergence,” where distinguishing between digital and real becomes increasingly challenging.

Key Insights
- The Evolution of Networking: Networking wasn’t an inherent feature of early personal computers; it emerged over time through the development of protocols like Ethernet, invented by Bob Metcalf. This innovation allowed computers to communicate within local area networks (LANs), and later, wide area networks (WANs) expanded this connectivity across greater distances, setting the foundation for the internet as we know it.
- The Slow Birth of the Commercial Internet: Despite the buzz around networking in the 1980s, it took over a decade for the commercial internet to gain traction. The development of TCP/IP protocols and the first browsers like Mozilla and Netscape in the early 1990s played pivotal roles, making it possible to connect diverse systems and leading to the first commercial internet experiences around 1994.
- Media’s Transformation Through Technology: The shift from traditional print to digital media was not immediate. Early digital publications like InfoWorld Electric struggled with how to translate print paradigms to the online world. This evolution highlights how media organizations had to rethink content distribution, design, and audience engagement as technology advanced.
- The AI Hype Cycle Mirrors Past Tech Booms: The current excitement—and anxiety—surrounding artificial intelligence mirrors past tech hype cycles. Just as people overestimated the immediate impact of networking or social media in their early days, today’s AI discourse is filled with grand predictions. The key insight is that while not every forecast will materialize, genuine transformative value emerges over time when technologies integrate into daily life.
- The Concept of the Third Convergence: The episode introduces the idea of the “third convergence,” a future phase where the line between digital and physical realities blurs. This convergence builds on past shifts like the integration of computing with media and the rise of social networking, predicting that immersive technologies, digital avatars, and augmented experiences will redefine how we perceive and interact with the world.
- The Importance of Timing in Technological Adoption: Many technologies that seem revolutionary often take years, even decades, to achieve mainstream adoption. The comparison between the slow rise of networking and the gradual acceptance of streaming services like Netflix underscores the importance of infrastructure, user readiness, and societal shifts in turning potential into reality.
- Lessons from Tech Visionaries: Personal anecdotes about figures like Steve Jobs and Elon Musk reveal how their unique personalities influenced their business decisions. Jobs’ relentless focus and ability to reshape Apple’s trajectory, combined with Musk’s audacious risk-taking with ventures like X.com and PayPal, illustrate the complex interplay between visionary leadership, timing, and market dynamics in driving technological breakthroughs.
Episode transcript
Hello and welcome to Stuart Squared, where the younger generation me, the millennial, interviews the older generation, the baby boomer, about the history of technology from PCs to AI. The millennial is Stuart Alsop III, me, born in 1985, and the baby boomer
Welcome to the Stuart Squared podcast, where me and my father talk about what happened in the 1980s, the 90s, the early 2000s and the tens to understand where AI is headed based on the past of where the personal computing revolution went. So excited to dig into another topic with you, particularly around networking today. So what is networking?
Wow. So I have to roll way back based on what you just said in terms of the introduction, because when personal computers introduced, were introduced, there was no networks at all. Computers operated on their own. They could be directly connected with a wire, but there was no protocol for connecting any two computers together. And so when I got involved with the personal computers industry in 1980, there wasn't even a concept of networking. And previously, the way that computers were shared is you'd have a mainframe or a minicomputer with terminals, and there would be more than one terminal connected to the same computer that was not. So network inherently means that any one computer can talk to any other computer. Talk to is a term they have to be careful with, that can communicate with through some kind of protocol. And there needs to be a protocol for it to work with any two different kinds of computers. And that's a process that took a very long time. So we used to.
