A.I. is changing the ways war is waged. This week, we explore how the U.S. and Israel are using A.I. to identify targets in the conflict with Iran — and why data centers and fiber optic cables are targets on the front lines. Then, researcher Julie Bedard breaks down “A.I. brain fry,” a new condition she and her colleagues studied among A.I. users at work. And finally, Casey shares his battle with Grammarly after the company used his identity in a new A.I. feature, without his consent. Guest: Julie Bedard, managing director and partner at Boston Consulting Group who is also the lead author of a survey of “A.I. brain fry” in the workplace.
