Apologies for that not being clear. Given I had linked to the original article in the first sentence, I took the perspective of people knowing which "CSP" I was talking about. I'll update the post in the morning to spell/link out to the first CSP reference.
If you ever have a post-Communicating Sequential Processes journey at GitHub, please do write a post! Most people I know are moving to something CSP based (say, Go channels) so it would be very cool to understand why someone would consciously decide to ditch the concept again, after a serious engineering effort.
