The document discusses the concept of a "transparent web" where the distinction between client-side and server-side code is minimized. It provides examples using Opa and Ur/Web programming languages to demonstrate "Hello World" programs that can compile and run code on both the client and server without needing to manage separate codebases. The document argues this approach can help address common problems with web applications like security, managing multiple languages, and taking on system administration tasks. It acknowledges some may be hesitant but argues the benefits of increased productivity and reduced errors will lead to this approach becoming standard.
