Toffler made predictions about culture and society, not tech. He "predictions" were about about the impact of tech on the systems of society and culture as dictated by the major waves of tech evolution since the dawn of man. The Third Wave outlines the waves of history, Future Shock is about the friction of assimilating to rapidly changing tech and culture, Powershift is about the shift in power from a top down system to a producer-consumer system due to decentralization and Revolutionary Wealth is about the revolution where new business and economic models emerge such as patreon, bitcoin and the Gig economy. I recommend all of these books as they outline a framework for understanding the nature of the technological imperative.
