I Love the bending analogy. Big old oaks will break off or pull up their roots while willows bend in string winds.

Long volatility: building systems which can survive and thrive in gusty circumstances. A challenge is that a long volatility strategy classically has extra costs when it's calm. Is it ever calm in this second decade of 2k?

I spoke a couple weeks ago with a person working to update a system I designed and worked on in the early part of the 21st century. It was built with an extreme programming approach. There were unit/programmer tests first. The metaphor was defined, if not obvious to all devs. Shared code, customer on promises, customer acceptance tests, etc. I attempted to design for long volatility without knowing the words. Did it work? 25 years is a very long time.
