You continue to express strong claims on strong claims without backing a single one of them up. And then you drop to mocking others for challenging those claims.

Have you ever heard the saying, “assertions made without evidence can be dismissed without evidence?” My experience differs.

Immutability has been the foundation of many of our large scale programs. It makes safe concurrent programming easier, and languages built around immutable data structures usually optimize memory handling in ways that are not available when simply writing “functional style” code in non-functional languages. ie under the hood they’re using persistent data structures, structural sharing, tail call optimization, etc.
