Kurzweil argued that information technologies improve exponentially, and that progress speeds up as each new paradigm takes over from the last. Here are 31 curves an investor can underwrite, each plotted on a log scale so the doubling time reads straight off the line.
Years for a 10× change, from a log-linear fit over each series’ fit window. Shorter bars compound faster. Select a row to jump to its chart.
Linear scale: each chart now shows raw values. Most curves look flat for years and then shoot up, which is the intuition gap Kurzweil describes. Fitted rates are unchanged.
