Neil Postman's lecture distills a lifetime of thinking about technology into five principles for evaluating technological change. First, all technology involves trade-offs—every benefit comes with corresponding costs, though promoters emphasize only benefits. Second, the advantages and disadvantages of technology are never distributed evenly—some people gain while others lose, and those decisions are political rather than inevitable. Third, embedded in every technology is a powerful idea, often unexamined, about what matters and how the world should work. Fourth, technological change is ecological, not additive—a new technology doesn't just add to existing culture but transforms everything around it. Fifth, technology becomes mythologized, treated as natural and inevitable rather than as a human choice that could have been made differently. Postman, a media theorist who coined the term 'technopoly' to describe societies that surrender human judgment to technological imperatives, developed these principles through decades of teaching and writing about how communication technologies—from the alphabet to television to computers—shape thought and social organization. His analysis provides tools for evaluating technological claims that remain relevant as each new platform promises transformation. Readers will find a framework for asking better questions about technology: Who benefits? What do we lose? What assumptions are built in? How will this change our culture? Postman's skepticism is not Luddite rejection but insistence that humans remain capable of choosing which tools to adopt and how.
