More than 4,000 jobs. That is what it costs to go all-in on artificial intelligence, at least if you are Jack Dorsey. The CEO of fintech group Block, the company behind payment processor Square, confirmed this week that the firm would slash nearly half its global workforce in one of the most candid admissions yet that AI is actively replacing human workers at scale.
Block's shares surged more than 25 percent in after-hours trading on Thursday following the announcement, a reaction that tells you everything about where investor priorities currently sit. Markets rewarded the decision immediately, even as thousands of employees absorbed the news that their roles had been rendered redundant not by poor performance, but by an algorithm.

Dorsey was blunt in a letter to shareholders. "Intelligence tools have changed what it means to build and run a company," he wrote. "A significantly smaller team, using the tools we're building, can do more and do it better. And intelligence tool capabilities are compounding faster every week." He added that he did not consider himself early to this realisation, but believed "most companies are late" and that a "majority" would reach the same conclusion within the next year.
Here's the thing: Dorsey is not alone, but he is unusual in saying the quiet part loudly. Amazon has announced layoffs totalling 30,000 roles since October, months after CEO Andy Jassy warned that AI would mean "fewer people doing some of the jobs that are being done today," particularly in white-collar work. Amazon, however, has been careful to play down the direct connection between those cuts and its AI investments. Dorsey has made no such effort at diplomatic distance.
The broader picture is sobering. In late January alone, Amazon, UPS, Dow, Nike, Home Depot and others collectively flagged a combined 52,000 job cuts. Economists and investors are watching US labour market data closely for signs of AI-driven structural change; the latest non-farm payrolls figures came in better than expected, suggesting the jobs market has not yet entered free fall. But individual corporate announcements are pointing in a consistent direction.
For Australian workers and policymakers, the Block announcement is a useful reminder that these shifts are not abstract or distant. The Australian Bureau of Statistics has previously flagged that administrative, clerical and some professional roles carry meaningful exposure to automation. If Dorsey's prediction holds, that a majority of companies will make similar structural decisions within twelve months, the downstream effects on employment, tax receipts and social services will eventually land here too.
There are genuine counterarguments worth taking seriously. Critics of the AI-displacement narrative point out that technological change has historically created as many jobs as it has destroyed, often in categories that did not previously exist. Productivity gains from automation can lower prices, grow markets and generate new demand for human skills. The Fair Work Commission and labour economists have consistently noted that transition, rather than net destruction, is the more likely medium-term outcome for most economies.
It is also fair to note that Block's decision was not made from a position of pure strength. The company reported fourth-quarter revenue of nearly $6.3 billion, in line with Wall Street expectations, but earnings fell sharply to just 19 cents a share after a $234 million write-down on its bitcoin holdings. The cryptocurrency dropped 23 percent in value this year, a painful result for a company whose CEO describes himself as a "bitcoin maximalist" and has long backed the digital currency over more cautious alternatives like stablecoins. Rival payment company Stripe, which bet on stablecoins, reported that its stablecoin transaction volumes increased fourfold over the same period.
So the question worth asking is whether Block's mass redundancy is a pure AI story or also a balance sheet story dressed up in the language of technological inevitability. The answer is probably both, and that complexity matters when assessing Dorsey's framing. As reported by the Financial Times, the workforce reduction comes despite what Dorsey characterised as a "strong" 2025 financial performance, though the bitcoin losses complicate that characterisation considerably.
What is clear is that the intersection of AI capability and corporate cost pressure is accelerating decisions that might otherwise have been phased in gradually. Reasonable people can disagree about the pace and permanence of these changes. But Block's announcement is one of the most explicit signals yet that for some companies, that calculation has already been made. The question for governments, regulators and workers is whether the policy frameworks designed for a slower-moving economy are anywhere near ready for the answer.
