I agree with you, even thought I might personally prefer Elixir/Phoenix :-)
In my particular case thought I've been opting for Golang given that my web app needs to perform a little more that CRUD. And in regards to the CRUD part I've been heavily relying on PostgreSQL functions, thus instead the pain of a ORM I just have simple raw sql `SELECT * FROM api.get_user_data(?,?);`
I'm not saying that is not possible to to things like this on Ruby, but when your application is a little more than CRUD RoR starts getting on my way...
