A popular article that does a good job on a technical subject -- that's rare, but the author pulled it off.

In the late 1970s, I decided to move from mathematics to business and/or public policy. So I wrote a thesis in game theory, extending von Neumann's MinMax Theorem, about a year after learning what the MinMax Theorem even was. So it's safe to say the mathematics of game theory was a bit thin back in those days, and I haven't heard of great progress in the intervening decades either.

As for applicability -- once again, the author got it right.
