Yes, I think Nash equilibrium will be way more influential in the long-term than Black-Scholes.

Neither one of them should be on there. Both rest upon the false assumption of human rationality. They are delusions masquerading as mathematical truth.

Black Scholes doesn't assume rational market participants.

It does make other bogus assumptions though. Normal distributions, risk free interest rates,...

I thought the problem with Black-Scholes is that it didn't factor in the use of Black-Scholes by participants.

That's an interesting perspective. And it's a perspective that would be familiar to any student of cybernetics and social systems theory: http://en.wikipedia.org/wiki/Second-order_cybernetics so-called second order cybernetics. Fascinating stuff I think.
