> Sometimes it makes me mad that so much confusion (and as another commenter put it, gatekeeping) has been sown in FP circles through the invention of pointlessly-obfuscated terminology for everything (and through - among many in those circles - a lack of interest in connecting the very simple dots that would allow masses of people to understand these concepts)

This is why people say "a monad is a monoid in the Category of endofunctors" as a joke whenever anyone posts an unnecessarily complicated explanation. This is the biggest and most visible flashpoint between people who don't understand, and the people who don't understand why they don't understand and think that defining things in terms of other things that you also don't understand is a viable strategy.
