Simon Willison highlights a questionnaire change when comparing US Census Bureau business AI-use figures over time. Among firms with at least 250 employees, the reported share appears to rise from roughly 12% in September 2025 to about 40% in October 2026. But in November 2025, the question expanded from producing goods and services to any business function, so the entire increase cannot be treated as adoption growth. A recent replacement of the term AI with “Super Intelligence” is another change; results using that wording have not yet been released.
