AI saves about 3% of your hours, and almost none of it reaches the money
A study analyzing AI productivity gains found that AI saves workers roughly 3% of their hours, but that most of these time savings do not translate into measurable financial returns or revenue generation for companies.
Background
- The article analyzes real-world productivity gains from AI tools (ChatGPT, Copilot) in knowledge work, citing a 2024 MIT/Stanford/Upwork study: AI saved about 3% of workers' time on average, with minimal impact on revenue or profit.
- "ROI" (Return on Investment) measures whether money spent on AI yields measurable financial gain. The article argues most gains are "inframarginal" — they improve easy tasks but don't free capacity for valuable new work.
- "Almost none of it reaches the money" means saved hours rarely become cost savings or extra revenue. If employees work the same hours and just finish a bit faster, the firm sees no financial benefit.
- The author (anonymous, Okaneland blog) takes a skeptical, data-driven stance toward the AI boom. Since late 2022, massive corporate investment in generative AI has been justified by claims of dramatic productivity gains — claims this article challenges with specific numbers.
