Anthropic has released the most comprehensive data yet on who is using AI and how, in a report titled "Anthropetic Economic Index: Learning Curves," which found that experienced users achieve better results from an AI model than newcomers. The study also revealed that AI will be a significant threat to casual or unsophisticated users who fall behind their more AI-savvy peers. This gap is not explained by the user's tasks, location, country, or model used, but it is a class gap in real time. The report's release comes amidst the most anxious era Americans have experienced about AI and jobs since OpenAI's ChatGPT release in 2022.
