I can see your point, and while I'm not versed in Go or Erlang, moving to JS let me stop worrying about if a value ever changed - as long as I'm in my portion of code, I alone can change the values. That, in turn, means that I spend very little time worrying - much less than I did in, say, Java. Sure, I need to not BLOCK stuff for long, but that comes about somewhat naturally as good code: Write small, discrete units. Not knowing modern multithreaded languages may render my entire point moot. I'll have to fix that.
