BBC writer Spencer Kelly recently had a piece on futurists. Ironically, I was on a plane coming back from London, so I missed it when it first came out.
The one good point it makes about the field is that there's a structural incentive to sound radical. No one wants to pay a futurist to say that the future is going to be incrementally different from the past. As technology journalist Tim Phillips puts it,
The problem is that if you're a futurologist there's no point in playing it safe. You have to be revolutionary and radical, you have to sell a big idea, or else what's the point of you? The problem is revolutionary, radical, big ideas very rarely come true.
A good summary of the futurists' professional paradox– one that, I should add, we've created for ourselves.
