For the record, I spent 10-12 years coding Java (the last 4 or so w/ Spring). Lots of OOP, lots of pattern based enterprisey big boy stuff. I definitely have a solid (but atrophying) understanding of the concepts. I get that they're the right way to do big Java apps. But Java makes implementing them fucking laborious. Back when that was all I knew, it seemed elegant and I was used to the scaffolding.. but the truth is that in a number of other languages the same patterns require so much less scaffolding and even thought, that we don't even notice them. They're a given.

I give my users vastly more value-per-line-of-code now than I ever did writing Java.

That said, I have nothing against Java or folks that enjoy doing it... but even when it was a language that I was knee deep in and stoked on, I was able to laugh at some of the shark-jumping complexity of these cartesian products of patterns that would arise.
