The concept of sharing code is being redefined by "repl" programming, which allows for immediate execution and continuous revision of code, making it more social and collaborative than traditional private code sharing. This shift towards shareable computing is expected to radically change the world of programming, moving more code out of private repositories and onto the public web, and ultimately making app stores and walled gardens obsolete. As repl-based social programming becomes more prevalent, it will also alter internet architecture, rendering Domain Name Service and web hosting services redundant, as repls can display output from any location.
