I think he&#x27;s referring to how Erlang uses the Actor Model. An Erlang program consists of (possibly) thousands of individual lightweight-processes. In this model a typical task may be spread out over many asynchronous processes. You can think of it as a program thats made up of thousands of micro-services. Instead of a task taking place over a sequential piece of code, it takes places over many individual processes that coordinate by communicating with each other.
