Good point.<p>Although, I never really was able to reconcile Thiels&#x27; criticism of an &#x27;indefinite&#x27; worldview. It appears to me if the factors that influence things are not only the unknowns but the are unknown unknowns (i.e. you don&#x27;t even know what you would need to know that will determine the fate of the company&#x2F;country&#x2F;whatever). In that case, how could you be anything but uncertain and just try to structure your life to benefit from convexity or as Taleb coined, anti-fragility?
