Before smartphones became standard, unshielded computer speakers often picked up interference from nearby 2G mobile phones, buzzing seconds before a call or text arrived. People joked that the speakers could tell the future because the warning came first. The clip spread through early forums, videos and soundboards as a shared memory of that era. It survives now less as a real everyday noise and more as a meme shorthand for incoming trouble, a prediction coming true, or technology giving away what happens next.
