“Hiring in back-office functions such as human resources will be suspended or slowed; of the roughly 26,000 non-customer-facing roles at IBM, "I could easily see 30% of that getting replaced by AI and automation over a five-year period" — roughly 7,800 jobs.”
The five-year window runs to May 2028. IBM has since said AI agents took over work previously done by a few hundred HR staff while the company hired in engineering and sales, so the 30%/7,800 figure is not yet settled.
