Happy Sunday, friend. There’s a fine line between “just a gadget” and a total tech revolution, and sometimes, that line is literally made of glass. Back in 2006, Steve Jobs had one of his legendary mic-drop moments: “I want a glass screen, and I want it perfect in six months.”

Take a guess why he really wanted the iPhone screen to be made of glass? A) Steve Jobs hated microplastics, B) It got scratched by keys in his pocket, C) Apple got a discount from Corning, or D) The prototype melted in heat. Answer’s at the end.
