For a few days in late February 2026, the abstract became concrete. Two viral essays - one a 5,000-word warning viewed 85 million times, the other a financial thought experiment predicting economic collapse - collided with Jack Dorsey cutting 40% of Block’s workforce. The Dow dropped 800 points in a single day. Software stocks cratered. And for the first time, Wall Street had to price in the possibility that AI might actually displace white-collar workers at scale.
Then came the rebuttals. The market bounced. Block’s stock surged 14% the day after the layoffs. The “AI scare trade,” as traders started calling it, revealed something important: we’re still figuring out whether to believe the hype or dismiss it.
The Spark: Two Essays That Captured the Moment
It started with Matt Shumer, an AI entrepreneur whose February essay “Something Big Is Happening” compared AI’s current moment to February 2020 - the last few weeks before COVID-19 changed everything. Shumer argued that AI capabilities had crossed a threshold most people hadn’t noticed, with systems now capable of creating self-improving tools. The essay hit 85 million views on X, making it one of the most-read pieces of tech writing in years.
“If you’re saying ‘this won’t happen to me,’ reevaluate your thoughts now,” Shumer wrote.
Then on February 22, Citrini Research published “The 2028 Global Intelligence Crisis,” a detailed scenario of economic collapse driven by what they called a “human intelligence displacement spiral.” The thesis: AI agents replace software engineers and middle managers, companies reinvest the savings into more AI compute, which accelerates further layoffs in a feedback loop with no natural brake. In Citrini’s scenario, the S&P 500 falls 38%, unemployment hits 10.2%, and the consumer economy stalls because there’s no one left to spend.
The essay got 50 million views. ServiceNow dropped 3%. DoorDash fell 6%. Credit card stocks slid 4-8%.
The Confirmation: Block’s 40% Cut
On Thursday, Jack Dorsey made it real. Block announced it was laying off approximately 4,000 employees - 40% of its workforce - explicitly citing AI.
“Intelligence tools have changed what it means to build and run a company,” Dorsey wrote.
This wasn’t the typical “streamlining operations” language companies use to dress up cost cuts. Dorsey was making a statement: the machines are doing the work now. Whether or not that’s entirely true, the market believed it enough to send Block’s stock up 14% the next day. Investors rewarded the layoffs.
The timing couldn’t have been more combustible. A viral essay warning that companies would cut workers to fund AI, followed by the loudest example yet of exactly that.
The Rebuttal: Citadel Says Calm Down
Citadel Securities fired back within days. Their analysts argued that Citrini’s essay was built on “ignorance of macro fundamentals,” not genuine analysis of AI’s economic effects.
The hard data, Citadel noted, tells a different story: Indeed job postings for software engineers are up 11% year-over-year in early 2026. Daily use of generative AI at work has remained “unexpectedly stable,” showing “little evidence of any imminent displacement risk.”
Citadel’s core argument: AI displacement at scale would require “orders of magnitude more compute intensity than current utilization levels.” When AI compute costs rise above human labor costs, substitution simply won’t happen. There’s a natural economic boundary that the doom scenarios ignore.
They also invoked John Maynard Keynes: productivity shocks expand the consumption frontier. Humans don’t just lose jobs - they shift into new ones, often higher-quality ones. That’s what happened with every previous wave of automation.
The Real Fear: Ghost GDP
But Citadel’s rebuttal missed what may be the most unsettling part of Citrini’s argument: the concept of “ghost GDP.”
In the scenario, economic output keeps growing, but the gains flow primarily to owners of computing infrastructure rather than circulating through wages and consumer spending. The economy looks healthy in aggregate while large segments of the workforce experience permanent contraction.
This isn’t science fiction. Insurance company Liberate is already processing 2.8 million automated claims per month. Allianz and Travelers have disclosed major AI-driven savings. When companies can automate claims processing, customer service, and middle management, the question isn’t whether jobs disappear - it’s where the savings go.
If the answer is “mostly to shareholders and AI infrastructure investment,” the consumer economy has a problem.
What Actually Happened
By Friday, the panic had subsided. Markets recovered. The viral essays started attracting counterarguments from economists, AI researchers, and investors who pointed out the speculative nature of the predictions.
But something shifted. Congress is now reportedly planning hearings on “AI Labor Standards” for later this spring. Companies are being more explicit about AI-driven cuts. And investors have added a new factor to their models: the possibility that white-collar automation might actually accelerate faster than anyone expected.
The week didn’t prove that AI will destroy the labor market. It proved that the market now takes the possibility seriously enough to trade on it. That’s the real news.
The Uncomfortable Middle Ground
The most likely outcome isn’t Citrini’s collapse or Citadel’s reassurance. It’s something messier: uneven displacement that hits some sectors hard while creating opportunities in others.
New job titles are already emerging - Chief AI Officer, computational geneticist, predictive maintenance engineer. An electrician working in data centers can now make $250,000-$300,000 a year. But these roles require retraining, relocation, and adaptation that won’t happen automatically.
The essays and rebuttals that dominated February revealed a market and a workforce that genuinely don’t know what’s coming. That uncertainty is now a tradeable commodity. And until we see more data on actual displacement - not forecasts, not thought experiments, but real job losses and real new hires - the scare trades will keep coming.
