One David X. Li has come forward and admitted his role in the Wall Street crash. He wrote a mathematical model of the economy, and it accurately predicted what would happen. Until it wasn't. Small differences were noticed, but it still worked well, so they were ignored. Then everything stopped working. Why? Because the model worked too well. Everyone started using it. Obviously, when everyone does the same thing on the market, things don't work well. Even worse, the model was based on the old methods of economics-- it didn't predict it's own use.
But it's not really David's fault here. He wrote a mathematical formula that could be used to model the economic market. A few investors started using it to get an edge. But then the secret got out, and everybody started using it. Wall Street investors were too interested in short-term gains to think about what would happen. Blame them.
