Some books, movies and TV shows become terribly dated, boring and annoyinng, while others withstand the test of time. I believe that within ten or fifteen years, a remarkable collection of entertainments will get painfully dated due to a single invention. Let me illustrate. I was watching a procedural mystery, a TV show from the 1970's. The attorney is awaiting a call from the detective, who is waiting for a call from his father to tell him that the missing witness has called his father. All these people of course, keep checking in with each other whenever they can find a telephone.
How much of this can we bear? They all ought to have cell phones! The harder it gets to understand life without cell phones, the harder it will be to empathize with people who lived entirely without them.
