Explaining Monads in the Post-Apocalypse
Description
A single-panel, black-and-white cartoon depicts a man in a tattered business suit sitting with three children around a small campfire. The setting appears to be a desolate, possibly post-apocalyptic landscape with ruins in the background under a dark, cloudy sky. The man is gesturing as if explaining something profound. The humor is delivered through the caption at the bottom, which reads: "Monads are just monoids in the category of endofunctors". The joke hinges on the massive disconnect between the grim, survivalist setting and the highly abstract, academic nature of the topic being discussed. It satirizes the tendency of some highly specialized professionals, like functional programmers, to be so engrossed in their complex field that they lose all sense of context and audience. For experienced developers, it's a multi-layered joke: it pokes fun at the notoriously difficult-to-explain concept of monads, the impenetrable jargon often used to define them, and the archetype of the overly-intellectual programmer

The real post-apocalyptic horror isn't the zombies, it's finally understanding monads but having no one left to explain it to except children who think a 'functor' is a type of mutated squirrel
Civilization fell when the CI/CD pipeline broke, yet here we are, still huddled around the fire debating whether StateT s IO is a lawful monad - some incidents just outlive the infrastructure
After 20 years in the industry, I've realized the real monad tutorial fallacy isn't that everyone writes one after finally understanding them - it's that we keep pretending category theory explanations help anyone ship production Haskell code before the heat death of the universe
This perfectly captures the functional programming community's tendency to explain monads using the most academically rigorous definition possible, even when the world is literally burning. After 20 years of 'monad tutorials,' we've collectively decided that comparing them to burritos was too accessible - better to invoke category theory while civilization collapses. The real tragedy isn't the apocalypse; it's that someone will still insist on explaining the difference between Applicative and Monad before we can move on to survival strategies
The sacred FP rite: indoctrinating juniors with category theory before they discover >>= and regret it all
Monads: the only abstraction where “just” hides a PhD, three laws, and your entire side‑effect pipeline
Say “monoid in the category of endofunctors” in a design review and watch the meeting become eventually consistent - everyone nods, nobody commits
