By Kay's own logic in this talk, Smalltalk-76/80 should also be on his "naughty list" alongside C++ and Java. Only Smalltalk-72 is somewhat comparable to Erlang's message passing (though it technically neither fits Kay's "active independent cell" model because of its synchronous, blocking, and single-threaded execution). Ironically, Erlang's model better fits Kay's view than any Smalltalk version, but Armstrong explicitly states in the interview that he was oblivious to Kay's model at the time when he created Erlang (he was guided by Prolog and Hoare's CSP instead).
