In March 2025, Jack Dorsey said his layoffs had nothing to do with AI. Eleven months later, he fired 4,000 people and blamed AI. Both times, he was probably telling the truth

AI is genuinely transforming some jobs. But it's also becoming the most powerful corporate magic word since "synergy" — and Block is the clearest case study of both things happening at once. Here's how to tell which is which.

.

In March 2025, Jack Dorsey sent an internal memo explaining why he was cutting 931 jobs at Block. He was explicit: "None of the above points are trying to replace folks with AI." The cuts were about strategy misalignment and management bloat.

Eleven months later, he fired 4,000 people — 40% of Block's entire workforce — and told shareholders the opposite: "Intelligence tools have changed what it means to build and run a company."

The stock jumped 24% in a day.

Start with the org chart. Block grew from 3,835 employees in 2019 to over 10,000 during the pandemic. Dorsey built two duplicate corporate structures — one for Square, one for Cash App. The company ran nine product lines, including Tidal, a crypto wallet, and a music streaming service. Dorsey admitted on X he "incorrectly built 2 separate company structures" and "over-hired during covid."

That's not AI transforming a business. That's a correction years in the making.

But here's the thing: "we overhired and built a messy org chart" doesn't make your stock soar. "Intelligence tools" does. When Block employees were interviewed by Business Insider, seven out of seven said they had no clarity on how AI would actually replace their work. No deployed tool. No transition plan. Just a magic word in a shareholder letter.

Block isn't alone. Over 45,000 tech jobs were cut in Q1 2026, and about 20% of those companies explicitly cited AI. Forrester predicts over half of AI-attributed layoffs will be quietly reversed, and 55% of employers already regret making AI-attributed cuts. Even Sam Altman — the man who profits most from AI anxiety — called it out: "There's some AI washing where people are blaming AI for layoffs they would otherwise do."

But here's where it gets nuanced — because AI IS changing work. McKinsey now runs 25,000 AI agents alongside 40,000 humans and saved 1.5 million hours last year. Amazon, Microsoft, and Google are genuinely restructuring around AI capabilities. The displacement is real in specific roles — particularly administrative, analytical, and back-office support work.

The truth is messier than either narrative. Some companies are using AI to genuinely reinvent how they work. Others are using the word "AI" to dress up a garden-variety restructuring. The difference matters — especially if it's your job on the line.

IBM's CHRO told researchers that despite automating hundreds of HR roles, the company is tripling its young hires in 2026. Why? As AI researcher Gary Marcus put it: "You don't hire junior devs for their output. You hire them because the good ones grow into senior devs. The AI tools don't grow."

So when your company announces restructuring and says "AI" — ask one question: Which AI tool is replacing which specific task, and when was it deployed?

If the answer is clear and specific — a real tool, doing real work, already running — the change is genuine. Plan accordingly.

If the answer is vague — "intelligence tools," "the AI era," "the way work is changing" — you're not looking at a technology transformation. You're looking at a layoff with better branding.
