core.async != actors

A lot of folks here in the comments are confusing a channel system with actors. Channels can help with actor communication, but they are not the same thing. A problem with core.async in Clojure is that the scenario you describe is very simple to create. You’re managing channels and buffers (communication mechanisms) instead of managing logical modules that do work for you (actors).

If you want to succeed with actors, they need to really be a thing and you ideally want to abstract away the communication mechanism. This is what Erlang/Elixir have done and it’s beautiful. You don’t really spend a lot of time thinking about channels and buffers... you just talk to processes that are living things.
