Ring founder Jamie Siminoff is back at Amazon after a two-year break, now leading the tech giant's home security camera division as a VP. The division is called RBKS for its entities: Ring, Blink, Key (in-home delivery service), and Sidewalk (wireless network). And according to an email viewed by Business Insider, if employees at RBKS want a promotion, their applications will now have to describe how they use AI at work. Amazon isn't the only tech giant that's requiring the use of AI for promotions and performance reviews. In June, Microsoft also began considering formal metrics for evaluating how much employees use AI during the workday.
