> Shells are very programmable. A pro tip, if I may: never argue about programmability against a Lisp system. The argument unlikely to ever end up in your favor, because Lisp was designed from the ground up to be the ultimate programmable medium. The essence of Lisp lies in its incredible simplicity and flexibility - code is data, data is code, and everything can be manipulated programmatically. The development experience is unmatched. You don't even need to save things - you can just eval them in a scratch buffer and see instant results. The REPL is unbelievably good, making programming feel like playing a video game where you get immediate feedback for every action. This interactivity transforms coding from a write-lint-link-compile-run cycle into a fluid, exploratory conversation with your system. Sure, some things can be done equally well in shells, but not as nicely and elegantly as in a Lisp environment. The uniformity of S-expressions, the power of macros, and the ability to redefine anything at runtime give you a level of control that other systems struggle to match. Yours is a decades old argument yet Lisps are still prolific today, powering everything from Emacs configurations to modern web applications. The longevity speaks for itself - good ideas endure.
