This talk covers such an important concept of market forces and complexity and the resulting security externalities. It does so in a clean manner that can be widely understood. It reminds me of a [paraphrased] quote of Mike Walker, "that software tells the CPU what it cannot do".
It is both an explanation for the current state of affairs, and a call to arms to improve and look for simplicity and concise definitions of the needed functionality. As a proponent of LangSec, I heartily agree!
