“Financial options may be expensive because people know they
are options and someone is selling them and charging a price—but most
interesting options are free, or at the worst, cheap.
Centrally, we just don’t need to know what’s going on when
we buy cheaply—when we have the asymmetry working for us. But this property
goes beyond buying cheaply: we do not need to understand things when we have
some edge. And the edge from optionality is in the larger payoff when you are
right, which makes it unnecessary to be right too often.” –Nassim Taleb, Antifragile
