Lamport's paper was only the very beginning of distributed systems. And CSP was invented by mathematicians for themselves, not for real life programming. As opposed to Erlang, which was invented for real life programming of telephony applications later in 1980s. But people keep ignoring history and think that CSP is suitable somehow, and not actor model. CSP is an even bigger mistake, don't try to make it look like it isn't. Learn from history.
