I've read a good chunk of science fiction over the years, but the most accurate Cassandra I've talk to in my life was my aunt and her colleges whom were historians, futurists and history profs. Many of the recent big changes in the national and international economies and political environment were discussed/forecast by them over two decades ago. And a few science fiction writers have gotten some of these trends right, while failing on the little details like gadgets. Yesterday's historian is today's prophet. Instead of tracking the evolution of gadgets, tools and tools, it's more important to notice the social and political changes in one's lifetime. Many of those have been impacted by technology, not always a positive way when viewed on a macro-scale. While technology advances, basically civilization/society is still the same bunch of greedy primates that existed by the Tiber over two millennium ago.
