any firm with close substitutes will see its profits competed away. Nightclubs or restaurants are extreme examples: successful ones might collect healthy amounts today, but their cash flows will probably dwindle over the next few years when customers move on to newer and trendier alternatives. Technology companies follow the opposite trajectory. They often lose money for the first few years: it takes time to build valuable things, and that means delayed revenue. Most of a tech company’s value will come at least 10 to 15 years in the future.
