Do you know that these a lot of these libraries already exist as apart of the OTP platform? and that Erlang has been around for 35 years and because those libraries exists as apart of the platform by extension all the languages that run on the runtime have them too?

The JVM runtime is a runtime. BEAM/OTP/ERTS is a full fledged collection of middleware, libraries, and tools written into/as apart of the Erlang programming language. You can not separate one form the other.
