Succintly put, exactly this.

Scala is as bad/good as lisp, and has the same challenges.

It's fun for a solo developer or very tiny close-knit team to do intellectually fun code pirouettes and stunts. Not in a negative way, that does bring satisfaction.

But throw it into a multi-dozen people codebase with many varying styles and soon enough nobody understands what's going on and it becomes a royal nightmare.

There's a lot of value in simplicity if you need to maintain that code over the years and many people.
