The Principle of Least Resistance, protected from scrutiny by the metric black hole, supports work cultures that save us from the short-term discomfort of concentration and planning, at the expense of long-term satisfaction and the production of real value. By doing so, this principle drives us toward shallow work in an economy that increasingly rewards depth. It’s not, however, the only trend that leverages the metric black hole to reduce depth. We must also consider the always present and always vexing demand toward “productivity,” the topic we’ll turn our attention to next.
