I know "20y of professional practice in the industry expert"s who would look at you with a blank stare for such mastery of non-trivial abstractions, and yet not get it.

Good job is what I mean

I sometimes wonder if the "old" are just so set in their ways that they (unconsciously) don't want to learn anything new. Will has great power.

I don't know, but I have noticed two trends: for people who have worked x years, some have x years of experience, some have x times the same year.

Thanks haha, I had exposure to computers from a very early age, and I try to make functions/systems representing things I'm curious about. It's helped me grasp ideas and come up with new ones, and I should probably write about them more :P

As one of these guys (not yet 20 years experience but close), I concur. I don't accept defeat though as I'm actually trying to learn FP for the third time! I bookmarked this blog post for when I get to monads again.

Actually I'm fine with "lightweight" FP like Scheme or Elixir (HOFs, recursion, immutable data, etc.) but still struggle with "real" FP like Haskell or functional Scala (algebraic data types, monads, lenses, etc.)

By the way I couldn't help to notice that the blog also features a CSS centering article. The author really is into esoteric concepts!

Humility and self awareness is always inspiring. As well as starting to learn new concepts 20y in. Kudos!

for a good explanation what ADTs are useful for watch Effective ML by Yaron Minsky from 18:00 https://www.youtube.com/watch?v=-J8YyfrSwTk
