The term “inflection point” has multiple definitions. In differential calculus, an inflection point is a point on a curve at which the concavity changes from positive curvature to
negative curvature, or vice versa. In political science, an inflection point is a moment in history that dramatically alters a geopolitical situation, for better or worse. In business, Intel co-founder Andy Grove has described a strategic inflection point as “an event that changes the way we think and act.” Each of these definitions describes a moment at which our fortunes change — and in many cases, we can’t recognize the moment until
after it’s passed.
