Charles Stross Coins 'Barnum's Law of CEOs' as 87% Executive AI Use Outpaces 27% Frontline Adoption

Summary
Charles Stross argues executives are mandating AI tools from the top down even as worker-level evidence fails to show clear productivity gains.
A 2025 developer study he cites found coders thought AI made them about 20% faster, but measured trials showed them working roughly 19% slower.
The gap is also visible in adoption rates: about 87% of executives report using AI at work, versus 57% of managers and 27% of frontline employees.
Stross says that inversion points to labor-cost optionality and investor signaling—not proven output gains—as the main force behind corporate AI mandates.
The framing comes from a December 2025 blog post rather than original peer-reviewed research, though the statistics cited draw on third-party studies and surveys.
