In Go the aphorism is:

Don't communicate by sharing memory; share memory by communicating. 
and this is very right, something that has been known since the 1960s.
Do not do shared memory multithreading and dealing with the fall-out
(*), have all threads be either in a thread pool handling independent
tasks or only have processes with no shared memory.


(*) The only caveat would be for some operating system implementation
situations.
