Some people think differently from the rest of the crowd. The different thinkers don't do so well in times when the mainstream crowd has life all figured out. At such times the different thinkers are easy to spot. They're the ones doing crazy stuff, heading for disaster. Or ridicule.
But in times of rapid change, when the mainstream crowd are hanging on to modes of thought and behaviour that no longer work - that is when we need our different thinkers. In my opinion, that is why dyslexics and other kinds of people who tend to think differently are so valuable to society.
Take the example of the movie industry today. Digital production and digital distribution have arrived but the industry has not yet adapted. Or look at the the business of book publication. Or music. There is a tendency for people rooted in the way things were to see the new technology as a way of making slight modifications to the status quo. This is when the different thinkers shine.
I came across the following video on Chris Jone's blog. It is the work of two film makers Arin Crumley and Susan Buice, creators of Four Eyed Monsters. I this completely inspirational. If you are interested in the collision of old media and the new digital age, this is well worth the half hour it takes to watch.
