Well for me looking at Erlang code is akin to looking at 'vase or two faces' photo, due to lower case being atoms and uppercase being variable names. And I dislike having to change ',' to '.' or vice versa when editing lines. Though three ',' and '.' endings do have an elegance to them.
Elixir is nice in that it is similar enough to Julia that I can copy and paste pieces of code and make minor edits to translate. Even javascript is relatively similar if map/reduces are used. Python is a bit harder due to white space blocks and list comprehension.
Hmm, I have personally trained Erlang to half a dozen juniors and interns. Any person who knows basics of programming can pick it up and write/fix mundane business code in less than a month. And I am a horrible teacher.
