The AI Adoption S-Curve

What Is the Technology Adoption S-Curve?

Major technological revolutions rarely unfold in a straight line. Instead, they follow a pattern that economists and innovation researchers describe as the S-curve of adoption.

 

The curve begins slowly. A technology is introduced, early adopters experiment with it, and its capabilities are explored. During this phase, adoption grows incrementally. Costs are high, applications are limited, and the surrounding ecosystem has not yet developed.

 

Then something changes. Infrastructure improves. Complementary technologies emerge. Businesses begin to reorganize around the new capability rather than simply experimenting with it. Adoption accelerates dramatically.

 

This is the steep middle of the S-curve, where the economic impact of a technology becomes visible across industries and societies.

 

Eventually, the curve flattens again. Once a technology reaches widespread adoption, growth slows as the market approaches saturation.

 

This pattern has appeared repeatedly across history, from railroads to electricity to the internet. The early stages often appear underwhelming, leading observers to underestimate the eventual impact. Yet once the curve steepens, transformation can occur rapidly.

 

This dynamic is part of what I describe as the Utility Thesis - the idea that artificial intelligence represents the third great general-purpose utility of the modern economy, following electricity and the internet.

 

And artificial intelligence now appears to be entering this same trajectory.

 

Electricity: The Original Industrial S-Curve

The electrification of industry provides the clearest historical example of the S-curve in action.

 

Thomas Edison opened the Pearl Street power station in New York in 1882. The technology worked. Electric light bulbs illuminated buildings across lower Manhattan. Yet the broader economy did not immediately transform.

 

For decades, factories continued to rely primarily on steam power. Electric motors existed, but most industrial facilities simply replaced the steam engine with an electric motor while maintaining the same system of belts and shafts used to distribute mechanical power throughout the factory.

 

The productivity impact of electrification did not appear until manufacturers realized that electricity allowed an entirely different organization of production. Instead of powering an entire factory from a single engine, electricity could power individual machines directly.

 

Factories redesigned their layouts. Production lines were reconfigured. Electric lighting extended working hours and improved safety. Entirely new industrial processes became possible.

 

This transition took decades. Yet once electrification spread across industry in the early twentieth century, productivity surged. Economists studying the period have consistently found that electrified factories achieved double-digit productivity improvements compared with their non-electrified counterparts.

 

The lesson is straightforward. The invention of a technology and the transformation of the economy rarely occur at the same time. The impact arrives only when organizations redesign their operations around the new capability.

 

The Internet: A Faster Adoption Curve

The internet followed the same pattern but at a significantly faster pace.

 

The first widely accessible web browser, Mosaic, appeared in 1993. Within a decade, half of American adults were online. By the early 2020s, internet penetration in the United States exceeded ninety percent.

 

Yet the economic transformation occurred not when the internet first appeared, but when businesses began reorganizing around it.

 

E-commerce platforms reshaped retail. Digital marketplaces transformed travel booking, media distribution, and advertising. Entire industries emerged that had no analog in the pre-internet world.

 

The internet compressed the adoption timeline seen with electricity. What took electrification half a century occurred within roughly three decades online.

 

More importantly, the steep middle portion of the curve – the period of explosive growth – arrived even more quickly.

 

The same dynamics now appear to be unfolding with artificial intelligence.
