How AI is expanding what people do at work

AI is enabling workers to take on tasks traditionally done by other job roles, a pattern called task crossover (work historically associated with one occupation appearing in how people in another occupation use AI). Analysis of over 800,000 ChatGPT messages from U.S. users shows that 43.5% of occupation-specific messages involve tasks outside the user's own job, with some roles like customer service workers doing outside-occupation tasks 77% of the time, suggesting AI is reshaping which tasks different jobs include before job titles officially change.
