Yes, exactly; also, there's an acknowledgement of the influence of "SMALL TALK" at the end of Hewitt, Bishop & Steiger's original 1973 IJCAI paper as it appeared in print (https://eighty-twenty.org/2016/10/12/hewitt-bishop-steiger-i...).

Actors, Smalltalk, Monitors and CSP all co-evolved during the 1970s, with many of the principals visiting each other and exchanging ideas. Retrospectives like Brinch Hansen's (https://dl.acm.org/citation.cfm?id=155361) spell out some of the lines of influence.

Thanks, TIL
