Jim Kavanaugh, CEO of World Wide Technology, told CNBC that people are “too smart” to accept artificial intelligence won’t alter their work environment.

Business leaders shouldn’t “BS” employees about the impact of AI on jobs, Kavanaugh said, adding that they should be as transparent and honest as possible.

Kavanaugh, who has a net worth of $7 billion, stressed that overall he’s an optimist when it comes to AI and its ability to improve productivity.
