It's not every day that people can get published in one of the world's leading scientific journals by playing computer games, but Foldit is no ordinary game. The brainchild of Seth Cooper from the University of Washington, Foldit taps into the collective efforts of tens of thousands computer gamers to solve scientific problems.
The goal of the game is to work out the complicated three-dimensional structures of different proteins. Proteins are feats of biological origami; they consist of long chains of amino acids that fold into very specific and complicated shapes. These shapes can reveal how proteins work but solving them is fiendishly challenging.
Psychologists will get better and better at investigating what makes games fun, and then entrepreneurs will design work environments that feel like fun games. Combine this with increasing technology, AI, and robotics, and eventually work of any kind will eventually be completely optional, so people will only do it if they enjoy it.
