In an article on "Why Ruby won't become mainstream", Cedric Beust says this:

Have you ever come across Smalltalk or Lisp programmers? You know, these people who, no matter what you tell them, will always respond that "Smalltalk did that twenty years ago" or that "Nothing has been invented since Lisp". They listen to you patiently with an amused light in their eyes and when you're done talking, they will just shrug away your points and kindly recommend that you read up on a thirty-year old technology that was the last thing they ever learned and that has been dictating every single technical judgment they have offered since then.

I don't know any Smalltalkers who aren't familiar with Java and/or C#, as well as other languages. I find plenty of Java developers who live completely inside the Java bubble though. Sure, we Smalltalkers can be arrogant snots - but it's not due to a failure to learn anything new. Quite the contrary, actually.
