""Offloading" or decoupling UI from server side processing is a recipe for an incongruent app."

that's a major generalization/assumption

it really depends on the technologies you're using and your team; not everything is built using rails

besides we have web services now and isn't it good practice to decouple the view layer anyway (as little logic as possible)? I mean in many companies there are completely separate teams that handle just ui or serverside tasks
