What Other Languages Can Learn From BEAM: A Ruby Case Study

One of the core building blocks of the BEAM's concurrency story is the Actor Model. It's the foundation for Supervision trees, Agents and Tasks in Elixir, and GenServers.

A new kid on the Actor Model block has arrived. With version 3, Ruby has implemented their own version of the Actor Model. We'll explore what it learned from the BEAM, and where it needs to grow if it wants to let developers build world class, concurrent applications with it.
