One of the world's most resilient systems was written in Erlang (the AXD301)... and was dynamically typed at that, lol. Not to mention WhatsApp, Discord, and others. Based on a thread a few days ago, I think a lot of people who have never used FP before don't seem to realize that outside of Haskell, it's generally very easy to do state in functional languages. Also, they aren't constantly copying entire data structures every time you modify them which some people just refuse to believe for some reason.
