Raimo Niskanen's Insights on OTP Team's Update & Gen State Machine at Code BEAM SF 2018

In Erlang/OTP 19.0 a new gen_* behaviour targeted at writing state machines was introduced - gen_statem. With its much richer feature set and a more general event model it was intended to replace the gen_fsm behaviour.

This talk goes through the gen_statem features, how they differ from gen_fsm and plain gen_server, and why they make gen_statem a better tool for writing any state machine except possibly the simplest.
