This is pure argument from authority, but I'm gonna take the bait anyway. > Martin Fowler What has this guy done except writing books about "the best way to program" without ever designing a full system himself ? > Guido van Rossum, Yukihiro Matsumoto Those guys are just language designers, and the language they designed are just as questionnable as the functional ones, so why do they get a pass actually ? Because their languages are more used ? Do you want to follow suit and say that COBOL creators are probably part of the "world's most experienced programmers" ? What about PHP ? There are some good points and critiques about the practicality of functional languages, but you don't actually touch on any of them here.
