I find C/C++, et al curly brace syntax and semi colon at end of line, maybe; syntax absolutely abhorrent. Erlang reads like a sentence commas, and period at end. There's very little syntax and it makes sense. The problem it is different than what 90% people learned programming on (curly brace languages).

But the hard part of Erlang is OTP / understanding the concepts or rather unlearning the concepts from other programming paradigms.
