I often hear people claim they could build major products like Google or Stack Overflow in a weekend. While a basic prototype is easy, scaling to handle trillions of items, optimizing for revenue, and managing complex internationalization requires massive teams. Real businesses must address security, organizational inefficiencies, and subtle features that drive profit, making the gap between a weekend project and a viable competitor far wider than most realize.
