Meta's head of augmented reality software is stepping down from his role, a company spokesperson told Reuters on Friday, raising questions about the company's progress in developing a custom operating system for its planned AR glasses. VP of Engineering Don Box announced the end of his tenure at Meta internally this week, without elaborating on what he would do next, according to a source familiar with the matter. A Meta spokesperson confirmed Box would be leaving the company at the end of this week and said he was doing so for personal reasons.
