Over the Summer time break, Startup Each day is republishing key tales from 2025. This evaluation by QUT’s Cameron Shackell, compares the introduction and hype round electrical energy within the Twenties – and people who cashing in on it with AI at present, and the teachings to be taught, and was well-liked with readers when it got here out in October.
The electrification boom of the Twenties set america up for a century of business dominance and powered a worldwide financial revolution.
However earlier than electrical energy pale from a red-hot tech sector into invisible infrastructure, the world went by way of 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. But it surely’s already exhibiting a number of the hallmarks of electrical energy’s rise, peak and bust within the decade often known as the Roaring Twenties.
The reckoning that adopted might be about to repeat.
First got here the electrical energy increase
A century in the past, when folks on the New York Inventory Change talked concerning the newest “excessive tech” investments, they had been speaking about electrical energy.
Buyers poured cash into suppliers reminiscent of Electric Bond & Share and Commonwealth Edison, in addition to corporations utilizing electrical energy in new methods, reminiscent of 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 sooner 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.”
As we speak, the same international 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 “grew to become favourites within the increase though their fundamentals had been tough to evaluate”.
Market energy was concentrated. Large gamers used advanced holding buildings to dodge guidelines and promote shares in principally the identical corporations to the general public below completely different names.
US finance professor Harold Bierman, who argued that makes an attempt to control overpriced utility shares had been a direct trigger for the crash, estimated that utilities made up 18% of the New York Inventory Change 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.
Basically, electrical energy grew to become the backdrop to the market in the identical approach AI is doing, as companies work to develop into “AI-enabled”.
No surprise 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 progress, 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 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 Change’s unprecedented “Nice Crash”, which started on October 24 1929 and preceded the worldwide Nice Melancholy.
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 conflict in 1941.

The ripple results had been international, with most international locations seeing an increase in unemployment, particularly in countries reliant on international trade, reminiscent of Chile, Australia and Canada, in addition to Germany.
The promised age of shorter hours and electrical leisure became 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 value 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 finally acquitted – however 600,000 shareholders and 500,000 bondholders misplaced every thing.
Nevertheless, 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 grew to become 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 sooner than even these in search of to make use of it for enterprise or authorities coverage can typically manage properly.
Like electrical energy a century in the past, just a few 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 by way of their superannuation funds or alternate traded funds (ETFs).
Simply as within the late Twenties, at present’s regulation of AI continues to be unfastened in lots of elements of the world – although the European Union is taking a more durable 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 no one other bust, solely then adopted by reform?
If the parallels to the electrification increase stay unnoticed, the probabilities are slim.![]()
