The Acceleration
The <em>rate of change of the rate of change</em> — the second-order derivative that Toffler identified as civilization's defining variable and that the AI transition has driven into a regime the species has never previously inhabited.
The acceleration, in Toffler's strict sense, is not the speed of change but its acceleration — the rate at which the rate itself is increasing. It is a structural feature of a civilization in which the products of innovation become the tools of further innovation in a self-reinforcing cycle that has been operating, with intensifying force, since the invention of writing. The cycle cannot be interrupted without dismantling the civilization that produces it. What can be governed is the relationship between the acceleration and the organisms that must live inside it.
In The You On AI Field Guide
The empirical signature in the AI transition is visible in the capability curve. GPT-2 (February 2019) produced passable paragraphs that deteriorated into incoherence. GPT-3, sixteen months later, wrote essays and translated languages with startling fluency. GPT-4, thirty-three months after that, passed professional examinations. Claude 3.5 Sonnet, summer 2025, engaged in sustained context-sensitive collaboration on complex software. The interval between thresholds shrinks; the magnitude
