I dont know erlang. My hobby LLM project is having it write a fully featured ERP in Erlang.

An ERP is practically an OS.

It now has

- pluggable modules with a core system - Users/Roles/ACLs/etc. - an event system (IE so we can roll up Sales Order journal entries into the G/L) - G/L, SO, AR, AP - rollback/retries on transactions

i havent written a line of code
