                      What makes concurrency so hard?

This               page              is               about               :

The  short  version:  Concurrency is  difficult  due  to  the  state  space
explosion  that  occurs very quickly  when you distribute a  system,  which
exceeds our ability to model. 

The  author provides a neat demonstration of this hypothesis, and it really
resonates with my own experience. 

Recently, I’ve been thinking  about this  idea  a lot  since  I  discovered
Residual Theory[1]. In this theory, we begin with too  many possible states
to create  an accurate  model,  but  progressively reduce the complexity by
focusing on attractors[2],  solutions  that cover large areas of  the state
space, so that unforeseen states already have a solution.
