Finnish docent in Future research Mika Mannermaa has characterized our society as a "John Wayne-society". John Wayne, like the ordinary citizens of today, was outstanding at what he did and the prize tag of his expertice wasn't cheap. Anyhows, he's got a new book out, called "Out of Weak Signals, a Strong Future". Apparently, he feels that we're all surrounded by these weak signals, i.e. an idea or trend that will affect what business we do,and how. This trend is usually hard to perceive and is spotted by experts in the field.
There's an idea that I come across more and more often and perhaps that could be seen as a weak signal. The prediction is that the expert will be replaced by a generalist who knows a little bit of everything, instead of knowing everything in one tiny area. The idea is that people who have a broad perspective and a general knowledge of many things will do a lot better in life than experts concentrating on only one thing. (One reference in Swedish here.)
