Timeless. This book isn’t about the perils of technology. Postman isn’t arguing against progress. He is arguing against the loss of context, and the risk of modern thought turning everything into a measurable, quantifiable and rankable object. And the 30 years since the publication of this book have certainly validated his concerns.
This is essential reading even today. Some minor elements feel dated but his concerns about unlimited information without proper analysis, interpretation and contextualization are absolutely well founded and shockingly prescient.
