Go is based on C, so of course it is more familiar to many people, as most popular languages share that root (something for language designers to at least ponder). Lisps are hard to follow, too, if you aren't familiar with s-exp languages. If you had a prolog background, Erlang wouldn't feel nearly as overwhelming.
The hardest parts about understanding Erlang programs, IMO, are understanding message passing (already there with Go), supervisors, and managing state in a stateless system (the latter two aren't what I'd consider common idioms in other languages (though supervisors are easy to reason about due to operating systems). Understanding the syntax is something a short afternoon can resolve.
No idea at all why you're downvoted. I came to erlang after spending years working on a C++, actor model, message passing codebase. Unsurprisingly (although it was to me at the time) I felt quite at home.
The difficulty came from the new syntax and Erlang-style control flow. And as you say, those are entirely a matter of familiarity. I still find python to be more readable and writable, but by no means does that imply Erlang is not understandable.
