The electrification increase of the Twenties set the US up for a century of business dominance and powered a worldwide financial revolution.
However earlier than electrical energy light from a red-hot tech sector into invisible infrastructure, the world went via profound social change, a speculative bubble, a inventory market crash, mass unemployment and a decade of world turmoil.
Understanding this historical past issues now. Synthetic intelligence (AI) is the same basic objective expertise and appears set to reshape each side of the economic system. Nevertheless it’s already displaying among the hallmarks of electrical energy’s rise, peak and bust within the decade generally known as the Roaring Twenties.
The reckoning that adopted may very well be about to repeat.
First got here the electrical energy increase
A century in the past, when individuals on the New York Inventory Alternate talked in regards to the newest “excessive tech” investments, they had been speaking about electrical energy.
Traders poured cash into suppliers corresponding to Electrical Bond & Share and Commonwealth Edison, in addition to firms utilizing electrical energy in new methods, corresponding to Common Electrical (for home equipment), AT&T (telecommunications) and RCA (radio).
It wasn’t a exhausting promote. Electrical energy introduced fashionable motion pictures, new magazines from sooner printing presses, and evenings by the radio.
It was additionally an apparent financial recreation changer, promising automation, larger productiveness, and a future stuffed with leisure and consumption. In 1920, even Soviet revolutionary chief Vladimir Lenin declared: “Communism is Soviet energy plus the electrification of the entire nation.”
At this time, the same world urgency grips each communist and capitalist international locations about AI, not least due to navy purposes.

Then got here the height
Like AI shares now, electrical energy shares “turned favourites within the increase though their fundamentals had been troublesome to evaluate”.
Market energy was concentrated. Massive gamers used complicated holding buildings to dodge guidelines and promote shares in principally the identical firms to the general public underneath completely different names.
US finance professor Harold Bierman, who argued that makes an attempt to manage overpriced utility shares had been a direct set off for the crash, estimated that utilities made up 18% of the New York Inventory Alternate in September 1929. Inside electrical energy provide, 80% of the market was owned by only a handful of holding companies.
However that’s simply the utilities. As immediately with AI, there was a a lot bigger ecosystem.
Virtually each Twenties “megacap” (the most important firms on the time) owed one thing to electrification. Common Motors, for instance, had overtaken Ford utilizing new electrical manufacturing methods.
Primarily, electrical energy turned the backdrop to the market in the identical means AI is doing, as companies work to change into “AI-enabled”.
No surprise that immediately tech giants command over a 3rd of the S&P 500 index and almost three-quarters of the NASDAQ. Transformative expertise drives not solely financial development, but additionally excessive market focus.
In 1929, to replicate the brand new sector’s significance, Dow Jones launched the final of its three nice inventory averages: the electricity-heavy Dow Jones Utilities Common.
However then got here the bust
The Dow Jones Utilities Common went as excessive as 144 in 1929. However by 1934, it had collapsed to simply 17.
No single trigger explains the New York Inventory Alternate’s unprecedented “Nice Crash”, which started on October 24 1929 and preceded the worldwide Nice Despair.
That crash triggered a banking disaster, credit score collapse, enterprise failures, and a drastic fall in manufacturing. Unemployment soared from simply 3% to 25% of US staff by 1933 and stayed in double figures till the US entered the second world battle in 1941.

The ripple results had been world, with most international locations seeing an increase in unemployment, particularly in international locations reliant on worldwide commerce, corresponding to Chile, Australia and Canada, in addition to Germany.
The promised age of shorter hours and electrical leisure was soup kitchens and bread strains.
The collapse uncovered fraud and extra. Electrical energy entrepreneur Samuel Insull, as soon as Thomas Edison’s protégé and builder of Chicago’s Commonwealth Edison, was at one level price US$150 million – an much more staggering quantity on the time.
However after Insull’s empire went bankrupt in 1932, he was indicted for embezzlement and larceny. He fled abroad, was introduced again, and ultimately acquitted – however 600,000 shareholders and 500,000 bondholders misplaced every thing.
Nevertheless, to some Insull appeared much less a legal mastermind than a scapegoat for a system whose flaws ran far deeper.
Reforms unthinkable through the increase years adopted.
The Public Utility Holding Firm Act of 1935 broke up the massive holding firm buildings and imposed regional separation. As soon as thrilling electrical energy darlings turned boring regulated infrastructure: a reality mirrored within the humble “Electrical Firm” sq. on the unique 1935 Monopoly board.
Classes from the Twenties for immediately
AI is rolling out sooner than even these in search of to make use of it for enterprise or authorities coverage can generally handle correctly.
Like electrical energy a century in the past, a number of interconnected companies are constructing immediately’s AI infrastructure.
And like a century in the past, buyers are piling in – although many don’t know the extent of their publicity via their superannuation funds or alternate traded funds (ETFs).
Simply as within the late Twenties, immediately’s regulation of AI continues to be unfastened in lots of components of the world – although the European Union is taking a more durable method with its world-first AI regulation.
US President Donald Trump has taken the other method, actively reducing “onerous regulation” of AI. Some US states have responded by taking motion themselves. The courts, when consulted, are hamstrung by legal guidelines and definitions written for a unique period.
Can we transition to AI being invisible infrastructure like electrical energy and not using a one other bust, solely then adopted by reform?
If the parallels to the electrification increase stay unnoticed, the probabilities are slim.![]()
