Yeah noticed the same thing too - Ruby/Rails background, though I have done distributed systems in java (too many unnecessary abstractions in that ecosystem)
then you add the simplicity / lessons of clojure of using simple datastructures & functions - simply agents become frustrating - cz most of the things I need to get done are done in a few lines
majority of the time is spent thinking by me to save a few lines.
I have a Rails background, so maybe KISS is more engrained in my philosophy than whatever training material was used on AI. At least it isn't heavily pushing design patterns...
