From warehouse floors to corner offices, no role is off-limits to AI, says the CEO of the world’s largest private employer. “It’s very clear that AI is going to change literally every job,” Walmart chief executive Doug McMillon has warned.

AI is already reshaping the future of work with entry-level job seekers struggling to gain a footing—but Walmart’s CEO predicts more disruption is on the way. So much so that he can’t even think of a job description that won’t be altered by AI.

“Maybe there’s a job in the world that AI won’t change, but I haven’t thought of it,” McMillon told the Wall Street Journal.

With 2.1 million employees globally (including about 1.6 million in the U.S.), the retail giant offers a glimpse into how major employers are adapting to new technologies. And despite AI already automating some tasks for Walmart workers, including warehouse jobs, McMillon says the shift doesn’t necessarily mean people previously in those roles will be out of work.
