Bit of a strong claim when the Erlang/OTP was designed to handle massive concurrency without colorful methods. Given that both Erlang and Ruby are inspired by the message passing semantics of Smalltalk.

Unicoloured languages are great as long as your code doesn't have to actually do anything (which is lots of modern code, to be fair). Try writing a physics simulator or 3D renderer in Erlang and see how that goes.

  Erlang is not great at math performance, also because it uses arbitrary length integers. There is a nice comparison between several languages, including Erlang at https://stackoverflow.com/questions/6964392/speed-comparison-with-project-euler-c-vs-python-vs-erlang-vs-haskell https://stackoverflow.com/questions/6964392/speed-comparison... It all depends on how the code is written. Eventually somebody managed to make the Erlang code faster than the baseline C, then someone else made the C version 8k % faster, which proves your point. However, how is that related to using sync/async vs message passing?

However, how is that related to using sync/async vs message passing? If you want to write high-performance code then you need to be able to write synchronous code and have control over what your yield points are. If you take the "all calls are potentially async, runtime does what it wants" approach (i.e. "no function colouring") then you just will not be able to do that.

  The Wikipedia entry says Smalltalk was one of it's influences and Joe Armstrong, co-developer of Erlang, mentions message passing as the fundamental aspect of OOP that Erlang gets right.
