Evolution is slow. Java imho brought garbage collection to the mainstream. lisp had been doing that for 20 years or so.<p>I don&#x27;t think Haskell itself will ever be the language of choice, it&#x27;ll probably fall into (remain in?) a smalltalk like life.<p>That said, functional idioms seem to be creeping into lots of mainstream languages, so it&#x27;s not like <i>never</i>. Rust seems pretty heavily influenced by ml, and somewhat by haskell.
