I've never really had to program using Ruby but just reading this Concerns concept makes me shudder. Am glad that I do not have to deal with the code structured in such way.

I worked on Ruby fulltime in a large team and it’s as horrible as you imagine.

One big ball of connected modules that depend on everything else.

It’s not Ruby’s or Rails’ fault I guess, but it’s easy to screw up and do it badly.

You can make some pretty neat stuff with it but it takes great care and a lot of discussions and disciplined code reviews
