The author argues that the web is dead, killed by the rise of mobile apps. Apps are now how most people access online content through their phones, as typing URLs is cumbersome. Apps are focused on single tasks and keep users engaged through notifications and social features. However, apps follow an "economics of numbers" model where their success depends on acquiring and retaining large user bases. The author believes this makes apps feel like annoying "Tamagotchis" and that the web's distributed nature means it is not truly replaceable despite the current app trend.
