The problem is, so much of is BS that it's physically painful to keep up. Look, someone reinvented a basic lisp-ism in their mediocre language! Yes, new buzzwords for each part that was a function parameter to the original system! Yay! Now you can reduce your boilerplate by 10%!

The system is still an unmaintainable ball of mud, but at least your for() loops can now have ridiculously high jitter and concurrency landmines thanks to multicore use on a system bottlenecked by disk IOPs.

Part of you wants to play the curmudgeon and say "I like my old simple ways" instead of yelling "you idiots are spinning wheels on useless APIs instead of learning to do any actual engineering analysis on maintainability or performance." It's tough to balance!
