Sure, we can have a perfectly reasonable debate as to whether or not lazy-by-default is the best choice for a language. I personally like the laziness, but if Scala, or Closure, or ML, or Elm, or maybe by some act of god COBOL "wins" by taking the good parts, that's fine.

But here, we have an article trying to make some concept approachable - some math, not tied to a specific language. Maybe it's hard for most to follow, since it assumes the readers knows what a monad is. That's fair, but it'd be the same if it were Scala.

The top comment here - and a significant number of the upvoted comments here, and on every similar article - are just baseless attacks against the idea that people should learn this. Not questions or technical discussion, just attempts to ostracize the part of the community that finds it valuable. It's anti-intellectualism, plain and simple. Maybe it's the terminology, or the syntax, or because articles didn't show the lock before giving the key, but it is what it is.

Edit: Seriously, go re-read that top comment, from the condescending reference down to the assertion that it's all mental masturbation. In response to a post by a knowledgeable person trying to teach something useful to people who are interested. That's the top comment. Embarrassing.
