Three books by futurologist Alan Toffler: Future Shock (1970), The Third Wave (1980) and Power Shift (1990).
Toffler isn't discussed much nowadays, but his ideas of post-industrial knowledge economies, information overload, prosumers and techno rebels became common currency amongst a number of thinkers over the years, from Silicon Valley to 1990s China.
They're still part of our mental model of the early 21st Century, though the effects of his predicted changes on us may be less than he expected. It's fair to say he gave us a common language to discuss a range of changes, though whether they were sharp predictions or simply popular descriptions is a different question.
Pulp is full of predictions about the future, and its role in shaping our thinking is sometimes underplayed. But it's interesting to look at Toffler, or McLuhan, or Baudrillard or anyone else who prognosticates to see if some paperback author from the '20s or the '50s beat them to the punch.
