The AI Boom: Why History Doesn't Always Reward the First Investors

Every generation encounters a technology that feels unlike anything before it. Today, that's artificial intelligence. Corporate profits represent one of the largest shares of the economy in decades¹, and hundreds of billions of dollars are flowing into data centers and power infrastructure². It's exciting, and it could reshape the economy in ways we can scarcely imagine.

Many analysts describe AI as a long-term structural shift. But before betting the farm on it, it's worth remembering we've seen this movie before, several times. History offers examples of transformative technologies changing the world while many early investors failed to earn the returns they expected.

Railroads, Radio and the Internet

Railroads. In the 1800s they remade America, connecting a continent and transforming commerce. Yet one of the era's most prominent financiers, Jay Cooke, went bankrupt in 1873, contributing to a broader financial panic. The railroads kept expanding. The technology endured. Not every early investor did.

Radio. In the 1920s, RCA was viewed by many as one of the defining growth companies of its era. Broadcasting genuinely changed everyday life. The stock rose dramatically before falling roughly 97% from its 1929 peak, and the price didn't recover for decades³. The technology proved revolutionary. The price many investors paid for it proved far less rewarding, as outcomes depended heavily on when shares were bought and sold.

The internet. In the late 1990s, companies raced to lay fiber-optic networks, convinced they were building the infrastructure of the future. They were right; we rely on that infrastructure daily. But so much capacity was built so quickly that much of it sat unused for years, and several builders, including WorldCom and Global Crossing, ultimately failed. Many of the lasting winners emerged later, from a different direction. Google and Netflix built successful businesses on the back of the abundant, inexpensive infrastructure left behind.

Being Right About Technology Isn't Being Right About Price

The lesson: being right about the technology isn't the same as earning attractive returns from the companies tied to it. Markets and economies tend to adapt to transformative innovation over time, but the timing, the winners, and investor outcomes vary widely. Cisco, for instance, became one of the world's most valuable companies during the internet boom. After the bubble burst, its stock lost roughly 80% of its value and took 25 years to reclaim its prior peak, even as the underlying business kept growing⁴.

So how did history's most successful investors navigate periods like these? Surprisingly, many weren't necessarily better at predicting technology; they were simply more disciplined about valuation and risk. Warren Buffett largely sat out the late-1990s tech frenzy because he wouldn't invest in businesses he couldn't reasonably value, despite years of criticism for it. Stanley Druckenmiller, widely regarded as one of the greatest investors of his generation, later acknowledged that even though he recognized the signs of speculation, he got caught up in the market's enthusiasm near the peak. These examples are offered for illustration only and shouldn't be viewed as predictors of future outcomes.

What This Means for AI Today

None of this is a prediction that AI will, or won't, prove to be a bubble. It could become as transformative as the railroad or the internet. The more useful questions for long-term investors: Which parts of this ecosystem will ultimately capture the greatest economic value, chipmakers, software companies, energy providers, or businesses not yet created? And what price are investors paying today for growth that may take longer to materialize than expected?

That's the enduring lesson from more than a century of technological innovation. The scarce ingredient has rarely been information. More often, it's been the discipline to separate enthusiasm for a technology from the price paid to participate in it. Optimism and humility aren't opposing ideas; they can coexist, keeping investors focused on thoughtful, long-term decisions rather than emotionally driven ones.
