While go doesn’t have the fault tolerance built in the runtime, I do think that using an abstraction like genservers is a must in that language. While I don’t have that much go experience, I find that using raw goroutines is like using process primitives in elixir, prone to error (not to mention deadlocks) and a lot of scaffolding that is repeating itself.
As for the part of nodes implementation, this does seem to be very peculiar.
