Replace "Erlang" with any other language and the statement still holds true.

If you want the obvious explanation, it's because we all have different experiences, and no one tool will be the biggest win for all teams across all domains.

I mean, what you said about if statements (which should be very very rare in Erlang) kind of betrays it: you most likely _are_ holding it wrong.

Probably because they really are holding it wrong?
