> Symbols just appear you are supposed to know where from

While I don't like Symbols yes you are expected to know Ruby to at least a basic level if you wanna write Rails. It's like me saying in Node you are supposed to know Promises/async. Of course you are.

Also what were you using to support the concurrency before the switch? There are quite a few solutions out there you could have tried before doing a rewrite. Seems to me like you guys just wanted to write Node, which is fine, but it probably cost you quite some time.
