Predicting the future of communication

I just had the thought: Who would have predicted, thirty years ago, that in 2016 bookstores would still be thriving, but video stores would have all but disappeared?

I am reminded of this essay by Isaac Asimov, “The Ancient and the Ultimate”, that I read about 1980, but was written in the early 1970s, about the future of video technology. He was at a conference on communications and society, where a speaker was praising the new technology of videocassettes, and suggesting that authors such as him would soon be tossed on the scrapheap of history. The essay speculates about possible future improvements to video technology, inferring tongue-in-cheek that the pinnacle of the technology would be attained when it had turned into books.
