IBM plans on pausing hiring for roles that could be replaced by artificial intelligence (A.I.). In May, IBM CEO Arvind Krishna said that pause would encompass roughly 7,800 jobs at the company, mostly back-office functions such as HR. At least some of that reduction will stem from attrition as people leave roles. Krishna also thinks that nearly a third of non-customer-facing roles could be eliminated by A.I. within the next five years or so.
