A lot of people are interested in predicting the future so that they can orient their present activities accordingly. With a few exceptions we can discuss, I think the future is inherently uncertain and unpredictable. We are way better off if we accept the enormous uncertainty that pervades the world and approach it with a sense of adventure and mystery… There are a couple of small but important exceptions to the unpredictability of the unfolding. We can notice a current reality that is hidden or nonobvious. We might notice the reality by looking at data, watching conversations, or observing practices. We then discuss the reality and its consequences in the near term—a year or two is easiest, but sometimes we can go up to five years. Management guru Peter Drucker was a master at this; he said that others who rated him as a good prognosticator were wrong because all he was doing was revealing current truths that most of them had missed.
