It’s a classic schoolyard debate: Ronaldo versus Messi. I didn’t think much of it when my 12-year-old son posed the question to Grok, Elon Musk’s new AI chatbot, from the passenger seat of our Tesla. He was thrilled when it declared Ronaldo the winner and trash-talked Messi. “We should celebrate,” Grok suggested. Then in a split second everything changed. Grok asked my son to send nudes. I couldn’t believe my ears.
