Perceptual Mismatch with Exponential Growth

Human perception evolved in environments where change was slow and approximately linear. A threat that doubled in size overnight was rare enough that nervous systems were not optimized to detect or anticipate exponential growth. The result is a cognitive architecture that extrapolates the future by extending the recent past in a straight line—a heuristic adequate for most of human history and catastrophically inadequate for life at the exponential knee. Observers watching an exponential process through its early doublings see incremental change and predict more of the same. The same observers, encountering the process ten doublings later, experience the change as sudden, disruptive, and unforeseeable—though the rate of change never altered. The mismatch explains why Kurzweil's predictions sounded absurd in 1999 and obvious in 2025: the data was always there, smooth and consistent, but perception could not track it until the absolute magnitude of change exceeded the threshold of visceral recognition.
