it's usually those at the middle of the pyramid that get attracted to that complexity. once you climb further you revert to simple stuff that work effectively, because now you focus more on the essence than the apparent.

here's an example in haskell: https://www.willamette.edu/~fruehr/haskell/evolution.html

It takes self discipline to stop trying to make things more complicated than they need to be, but I think for me at a certain point you just lose interest in overcomplicating things. At least I have. I am much less interested in doing some new fancy thing in Haskell as opposed to solving it in a straightforward, effective manner.
