As artificial intelligence drives the conversation in Washington and on Wall Street, it’s having a growing effect across college campuses, too.

More than half of US college students say they’re using the technology in their coursework at least once a week, while one in five report using it on a daily basis, according to new polling from the Lumina Foundation and Gallup.

Those studying business, technology, and engineering are most frequent users of AI in their schoolwork — 70% of business majors, for instance, use it on either a daily or weekly basis. And that high usage is despite the fact that about half say their schools discourage using AI or bar its use among students.

AI is also driving sizable percentages of bachelor’s and associate degree students to rethink their major or field of study, though only 16% said they actually switched.
