As AI-generated videos, emails, and job candidates proliferate, our default assumption that what we encounter is human-made is collapsing, forcing us toward a zero-trust reality. On the way to work, you see a TikTok video of the president admitting to a crime. In the elevator, you hear your favorite band, but the song is completely unfamiliar. At your desk, you open an email from an executive in another department. It contains valid sales information and discusses a relevant legal issue, but the wording sounds oddly wooden. After lunch, the CEO sends all managers a link to a new app she had casually proposed just a few days earlier. Later, you interview a job candidate via Zoom, but the person looks different from his LinkedIn picture.
