Stanford: The AI efficiency-gain illusion
A recent Stanford study found the more people use AI, the more convinced they it is saving them time… when the results show it isn't and the price of that illusion is about to get a lot more visible for organizations.
The researchers tested nearly 2,700 people on exactly the kinds of tasks most Microsoft Copilot rollouts are built around.
Summarization
Rewriting
Simple information retrieval
Basic arithmetic
Short drafting tasks
Here's what the results found.
--> People used AI far more than they predicted… 47% of the time versus the 33% they expected
--> They believed AI would save roughly 56 seconds per task. It saved about 7
--> On the simplest tasks, AI actually made things slower.
--> And after using AI, people became even more likely to use it again — and more confident it was creating value — regardless of whether it actually was.
This isn’t efficiency. That's a belief of it. And it's costing organizations.
Most AI transformation programs are built on a simple assumption… Train people. Increase adoption. Drive usage. And the value will follow.
This study suggests something uncomfortable:
The tools and metrics many organizations are using to demonstrate progress may not be measuring value at all.
Usage may simply be creating more usage.
For the past two years, that distinction barely mattered. AI was effectively subsidized.
Uber recently disclosed it burned through its entire 2026 AI budget in just four months. Its COO admitted it's still difficult to draw a direct line between rising AI costs and customer value.
Uber won't be the last organization facing that question. The discounts they received to adopt those tools are quicky disappearing.
And leaders who built their business cases around adoption metrics are about to face a harder question:
Where is the business value?
Measuring AI activity is easy:
Training completion
Adoption
Active users
Prompt volume
Measuring AI transformation is much harder:
Workflow redesign
Decision quality
Knowledge architecture
Operational change
One creates dashboards. The other changes how work gets done.
And that's where many organizations are stuck.
Not deciding whether AI works.
Deciding whether they're willing to fund the foundations that allow more than a handful of strategic projects to succeed.
The foundation that creates lasting value isn't another tool.
It's the semantic layer, decision logic, governed platforms, and embedded expertise that enable teams to redesign work instead of simply accelerating it.
Usage without those conditions doesn't become transformation.
It becomes habit.
The organizations that scale AI won't be the ones with the highest adoption rates.
They'll be the ones willing to fund the foundations that make deep operational redesign repeatable.
