The electrification boom of the Twenties set america up for a century of commercial dominance and powered a world 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 stock market crash, mass unemployment and a decade of world turmoil.
Understanding this historical past issues now. Synthetic intelligence (AI) is the same general purpose technology and appears set to reshape every aspect of the economy. However it’s already exhibiting among the hallmarks of electrical energy’s rise, peak and bust within the decade referred to as the Roaring Twenties.
The reckoning that adopted could possibly be about to repeat.
First got here the electrical energy increase
A century in the past, when folks on the New York Inventory Trade talked concerning the newest “excessive tech” investments, they have been speaking about electrical energy.
Buyers poured cash into suppliers akin to Electric Bond & Share and Commonwealth Edison, in addition to corporations utilizing electrical energy in new methods, akin to Normal Electrical (for home equipment), AT&T (telecommunications) and RCA (radio).
It wasn’t a hard sell. Electrical energy introduced modern movies, new magazines from quicker printing presses, and evenings by the radio.
It was additionally an apparent financial recreation changer, promising automation, larger productiveness, and a future full of leisure and consumption. In 1920, even Soviet revolutionary chief Vladimir Lenin declared: “Communism is Soviet energy plus the electrification of the entire nation.”
Right this moment, the same world urgency grips each communist and capitalist countries about AI, not least due to military applications.
Then got here the height
Like AI shares now, electricity stocks “turned favourites within the increase though their fundamentals have been tough to evaluate”.
Market energy was concentrated. Large gamers used advanced holding constructions to dodge guidelines and promote shares in principally the identical corporations to the general public beneath totally different names.
US finance professor Harold Bierman, who argued that makes an attempt to manage overpriced utility shares have been a direct trigger for the crash, estimated that utilities made up 18% of the New York Inventory Trade 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 at present with AI, there was a a lot bigger ecosystem.
Nearly each Twenties “megacap” (the biggest corporations on the time) owed one thing to electrification. Normal Motors, for instance, had overtaken Ford utilizing new electrical manufacturing strategies.
Primarily, electrical energy turned the backdrop to the market in the identical method AI is doing, as companies work to develop into “AI-enabled”.
No marvel that at present tech giants command over a 3rd of the S&P 500 index and nearly three-quarters of the NASDAQ. Transformative know-how drives not solely financial development, but in addition 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 Average.
However then got here the bust
The Dow Jones Utilities Common went as high as 144 in 1929. However by 1934, it had collapsed to just 17.
No single cause explains the New York Inventory Trade’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 warfare in 1941.

The ripple results have been world, with most international locations seeing an increase in unemployment, particularly in countries reliant on international trade, akin to Chile, Australia and Canada, in addition to Germany.
The promised age of shorter hours and electrical leisure changed into 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 all the pieces.
Nonetheless, to some Insull appeared much less a prison mastermind than a scapegoat for a system whose flaws ran far deeper.
Reforms unthinkable through the increase years adopted.
The Public Utility Holding Company Act of 1935 broke up the massive holding company structures 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 at present
AI is rolling out quicker than even these searching for to make use of it for enterprise or authorities coverage can generally manage properly.
Like electrical energy a century in the past, a couple of interconnected firms are constructing at present’s AI infrastructure.
And like a century in the past, traders are piling in – although many don’t know the extent of their publicity via their superannuation funds or trade traded funds (ETFs).
Simply as within the late Twenties, at present’s regulation of AI remains to be free in lots of elements of the world – although the European Union is taking a harder strategy with its world-first AI law.
US President Donald Trump has taken the other strategy, actively reducing “onerous regulation” of AI. Some US states have responded by taking motion themselves. The courts, when consulted, are hamstrung by laws and definitions written for a unique period.
Can we transition to AI being invisible infrastructure like electrical energy with out a one other bust, solely then adopted by reform?
If the parallels to the electrification increase stay unnoticed, the probabilities are slim.![]()
