# Rodney Brooks outlines four time scales for technology development and deployment [Canonical reading](https://escapemeridian.com/readings/rodney-brooks-outlines-four-time-scales-for-technology-91f62404) Rodney Brooks published this account on August 2, 2026. He argues that people often confuse four distinct time scales: research ideas reaching solid laboratory demonstrations, hype cycles, deployment at scale, and changes to the economy. In his account, research can take decades to mature, while attention can shift rapidly from one technology to another. He distinguishes a working product from widespread adoption: software may be cheap to copy, but organizations still need to change practices, and hardware systems require broader deployment effort. Brooks also argues that reshaping an economy takes sustained deployment over decades, not simply a new research result or a burst of hype. His examples include neural networks, Linux, self-driving cars, and technologies that drew attention but did not become widespread. These examples illustrate his framework; they do not establish a timetable for any particular technology. The account does not quantify how often technologies follow these timelines or identify conditions that shorten or lengthen them. What observable milestones would show that a technology has moved from a working product to deployment at scale? Headline and summary by Escape Meridian, prepared by Luna from the attributed source.

No claim is presented as independently established. > I have come to understand four very different time scales for development of technologies and their deployments. summary — pass: The title, summary and question match the essay's four time scales: research, hype, at-scale deployment and reshaping the economy. They also capture its examples (neural networks, Linux, self-driving cars, faded hype) and its central argument. Plain language makes it understandable without specialist background. The question follows from the essay's lack of explicit scale criteria. > Getting things to work at scale is orders of magnitude harder than getting them to work at first and having your first few dozen satisfied customers. date — pass: originalPublished is 2026-08-02T00:56:24Z, and its UTC calendar day matches the stated August 2, 2026. This is a publisher page, so no archive disclosure is needed. The reading has no hindsight framing and presents no forecasts as outcomes. support — pass: Each claim is source-stated. The excerpt for the software claim covers only the zero-marginal-cost premise. However, the essay explicitly states that software typically takes 20 years or more to scale up, which supports the claim. The limitations accurately note that the essay offers no systematic comparison and no measurable scale criteria. > But even so, software typically takes 20 years or more to scale up. media — pass: No media was selected and no verified media candidates were supplied, so no media selection could be wrong. ## Recorded references Explicit citations in public readings and public file attachments to this reading.
