The Rapid Adoption of Generative AI
基于2024年底美国全国调查，发现45%的18-64岁人口使用生成式AI，工作采用速度超过个人电脑和互联网，目前辅助了1-7%的工作时间，节省了相当于总工时1.4%的时间，但行业和公司政策影响显著。
Generative artificial intelligence (genAI) is a potentially important new technology, but its impact on the economy depends on the speed and intensity of adoption. This paper reports results from a series of nationally representative U.S. surveys of genAI use at work and at home. As of late 2024, 45% of the U.S. population age 18–64 uses genAI. Among employed respondents, 27% used genAI for work at least once in the previous week: 10% used it every workday and 17% on some but not all workdays. Relative to each technology’s first mass-market product launch, work adoption of genAI has been faster than the personal computer (PC), and overall adoption has outpaced both PCs and the internet by an even wider margin. Between 1% and 7% of all work hours are currently assisted by genAI, and respondents report time savings equivalent to 1.4% of total work hours. Potential productivity gains vary widely by industry, and firm climate and policies play an important role in adoption patterns. This paper was accepted by Alfonso Gambardello, business strategy.
