I think if you ever find yourself saying Erlang is about one thing, you've lost the plot. Erlang has a bunch of features that each would be powerful in their own right, but they aren't special--there are other ways to solve the same problems, and some of those ways even have merit. But Erlang chose the set of features they did with a very high level understanding of how those varous features would interact. I honestly think it's one of the greater achievements humanity has accomplished. It lacks the obvious elegance that, say, Lisp, has, but I think the sum of parts in Erlang was probably a lot harder to make.
