My impression is that it is making a difference amongst top programmers. When I learned Scheme way back when in college, there was no pretense of it being practical. My AI professor said, "AI is reduced to LISP hacking" and that was to denigrate AI, not raise LISP. Nowadays people see the value of recursive thinking, and hence the value of functional programming. The convergence of many technology trends seems to suggest that the idea of "The program can be the data, and the data can be the program" is no longer so far fetched.
