Research is starting to suggest that productivity gains are linear instead of exponential. So, whenever there is a shift, such as industrialization, that facilitates productivity growth, the bulk of the gains compared against economic growth will come early on and comparatively diminish over time. It’s not that productivity growth declines, but that we’re comparing something that grows linearly (productivity) with something that grows exponentially (GDP).
