Top 10 Tech Predictions That Aged So Badly They're Now Legendary

From Steve Ballmer's prediction that the iPhone would capture zero percent market share to Kodak's conviction that digital photography would never replace film, these 10 tech predictions represent spectacular miscalculations by industry leaders who had expertise and resources. Each failure teaches concrete lessons: how experts underestimate consumer behavior, miss platform shifts, or misjudge adoption curves. You'll identify patterns—like overweighting incremental innovation, underestimating open ecosystems, and the blind spots of defending legacy business models. These aren't just entertaining mistakes; they're case studies in why even brilliant technologists struggle to imagine paradigm shifts from within the old one. Understanding how smart people got these so spectacularly wrong—and why—is the best defense against making similar errors when evaluating today's bold claims about AI, quantum computing, and workplace automation.
