On March 14, 2026, billionaire Mark Cuban revealed he's combating a tsunami of AI-generated cold emails flooding his Austin inbox by arming himself with a seemingly innocent Apple Mac Mini. No, it’s not a Mini fridge—it’s his latest spam-fighting weapon. Cuban explained on TBPN that AI bots are not just cold emailing him but subscribing him to random junk mailing lists like an overly enthusiastic telemarketer on digital steroids. His master plan? Train another AI to relentlessly smash Gmail's unsubscribe button, creating what he hopes is the robot apocalypse's first AI-on-AI email battle royale. He calls it a work in progress, while LinkedIn's CEO is relying on Microsoft Copilot to finesse actual people’s emails like it’s a full-time job. Cuban predicts inbox spam will peak, fail, and fall off once annoying AI cold emailers get bored, an optimistic forecast reminiscent of my dating app chats in 2020.
