It's been over a year since Obvious Architecture came out and over a year before that when Uncle Bob gave his talk on Ruby Midwest. People seem to just now be catching on.

I've gone really deep down the rabbit hole on these kind of highly decoupled design patterns in Obvious, clean architecture, functional programming, TDD and all of that and I realize now that Ruby is not the optimal language for this style of development and DHH and Rails' purpose is not the same purpose of clean architecture.

I go back and think about the original build a blog in Rails demos, which are great BTW, and I feel like Rails' strength is standing up an application quick and getting stuff done. Yes it can do TDD and clean architecture and all of that fun design stuff, but to be completely honest, it doesn't fit the community or the language as much as it should.

Ruby gives you a lot of amazing tools, but there are a lot of things that make clean architecture way nicer that you end up bolting on to Ruby. Stuff like immutability, type checking, and strong interfaces are not the norm in Rubyland. That is perfectly fine, but by the time you build all those tools, it's hard not to look at a language like Scala or Kotlin and see a lot of those things built in to the language along with a compiler and nice IDE support.

I love Ruby and I use it every day. I live in a Rails app most of the day and I've found ways to make to make the code beautiful, but fundamentally I don't think the Ruby community will ever truly get behind clean architecture. It really flies in the face of the reasons why most people use Ruby in the first place.
