It always stuns me when software developers say, "I don't know <language here>, so that isn't an option."

Good programmers don't learn languages, they learn methodologies. You don't learn how to program in Lisp, you learn how to program functionally with flexible syntax. You don't learn Objective-C, you learn how to write good code in a message-passing OO system.

Sure, the libraries can take some time to acclimate too, but this is our job! I just shake my head and sigh where I hear programming language is the barrier. I can never tell if it's a clever excuse for the press, or if people actually believe it.
