Three men are sitting on a raft

There are only coconuts to eat, but after a week a box of tin can foods land on the beach. Unfortunately none of the three have a can opener. First the chemist thinks up a process of saltwater that eventually opens the cans. But that unfortunately takes many months. The physicist invents a throwing device that throws the cans against a rock wall. Unfortunately, the cans are crushed against the wall and the food is spread all over the place.

Finally, it’s the economist’s turn. He just says: “Let’s just for a moment assume we have a can opener.”

Development in the future is too important to leave it to model-calculators with fleeting assumptions. We need other relevant methodologies to create the future.
