Argument: Functional programming is not useful for most apps (en.arguman.org)

Interesting website that skips all our pretence of "discussion" and goes straight to "argument" :)

The actual discussion is fairly thin, but has a good point in that business requirements are usually expressed in terms of state changes to records or physical objects.

Functional core, imperative shell. https://www.destroyallsoftware.com/talks/boundaries

Sure, enforcing the paradigm everywhere would be bad. So don't do that!

Functional programming as a strictly immutable lazily evaluated paradigm in which to do everything from the bottom to the top is not useful for most apps.

This "but" is a complete fail:

Lisp isn't a functional language. Lisp has mutable variables, mutable data structures, loops, goto, ... Lisp supports applicative programming with immutable objects where it is desired.

I hate these discussions. Most people are more productive by just using the tool that fits their needs.

Also some people could better work in a functional world and some can't.
