More employed Americans have used the artificial intelligence (AI) tool ChatGPT for work since last year, with the biggest increase among the younger portion of the workforce, according to a Pew Research poll released Tuesday. The survey found that 31 percent of employed Americans between 18 and 29 surveyed in February said they have used ChatGPT for tasks at work, up from 12 percent who said the same last March. The number of employed Americans who said they use ChatGPT for work decreased by age group. Twenty-one percent of employed adults aged 30 to 49 said they use it, up from 8 percent last year, and just 10 percent aged 50 and older said the same, up from only 4 percent last year. Overall, the share of employed Americans who have used ChatGPT for work rose to double digits in the past year — reaching 20 percent based on the February survey, up from just 8 percent last March. But in general, most Americans still have not used ChatGPT, according to the survey. Twenty-three percent of Americans said they have used ChatGPT. That amount is on the rise from July, when 18 percent said the same. Use of ChatGPT has particularly spiked among younger adults. Forty-three percent of adults younger than 30 said they have used ChatGPT in the February survey, compared to 27 percent of adults 30 to 49, 17 percent of adults 50 to 64 and 6 percent of adults 65 and older.
