The choice of the name ‘game theory’ was brilliant as a marketing device. I think it’s a very tempting idea for people, that they can take something simple and apply it to situations that are very complicated, like the economic crisis or nuclear deterrence. But this is an illusion. Now my views, I have to say, are extreme compared to many of my colleagues. I believe that game theory is very interesting, I’ve spent a lot of my life thinking about it. But I don’t respect the claims that it has direct applications… If I could repeat my life, I would probably follow my unfulfilled dream to be a lawyer.
