A lot of the advanced features you see in popular "cool, cutting-edge" languages like Python, Ruby, JavaScript, etc. - stuff like closures, functions as first-class objects, lambdas, filter/map/reduce, continuations - were pioneered by Lisp. If you know Lisp, and you look at such languages, it's obvious that the creators also knew Lisp, and when they needed their language to do something that it couldn't otherwise do, they adapted something from Lisp. Interestingly, many such features were not, or could not be, or have been only with great difficulty, adapted to older languages like C/C++.
It's taken fifty years for these modern languages to catch up to Lisp.
The same thing to a lesser degree can be said about Smalltalk. Lisp and Smalltalk's influence is not so much in being used directly to create applications, but in creating other languages.
