This year marks the 25th anniversary of the Y2K crisis, a moment in history characterized by widespread fears that computers would fail as the year rolled over from 1999 to 2000. As the anniversary arrives, many are revisiting the intense paranoia that surrounded the millennium bug, which had people across the globe worrying about potential chaos. From last-minute shopping sprees to massive preparations by local governments, the panic seemed very real. Now, looking back, we can see that what many anticipated as a potential disaster turned out to be one of the biggest non-events in history. Various media outlets and personal reflections recount how communities braced for Y2K, the memories of mass hysteria, and the lessons learned about technological dependency. Celebrations and retrospectives highlight how people managed to ring in the new millennium with relief rather than turmoil.
