While hunting in my archives for something else I dug up this exercise in scenarios. It was a small game Brian Eno and I played to loosen up our expectations of what might happen in the near future. We were both struck at how improbable current events would be to anyone in the past, and how incapable we are at expecting the improbable in the future.
This list of unthinkable futures -- probabilities we tend to dismiss without thinking -- was published 15 years ago in the Summer, 1993 issue of Whole Earth Review. Our intent was less to correctly predict the future (thus the silliness) and more to predict how unpredictable the actual future would be.
