If you're anything like me, given enough time you wonder if all the 'fluff' of OO is necessary as you seem to be writing code to satisfy the programming style rather than the domain problem. You'll then try FP and find it has its own pitfalls - especially around how complex the code can get if you have a load of smart Haskell engineers - and suddenly they have the same problems ('fluff'). Apparently at some point I'll have a similar move to Lisp and discover how complex the code base can be with multiple engineers (I'm 8 or 9 years into this engineering journey myself!).

My current goal with software is to write this as simply as possible that a junior developer with 6 months experience could read my code and know how to modify it.
