It's meant to be a way to gather common features into one place. If all your 
routes are meant to have CanCanCan protecting them from unauthorized access, 
then you may see this in the ApplicationController:

  unless: :devise_controller?
before_action :authenticate_user!
load_and_authorize_resource
  end

Which means that you won't forget to add that to your controllers and leave 
something important exposed to the public. There's lots of other useful stuff 
you can wedge in the ApplicationController that you need in all controllers, 
and thus only have to write once. Inheritance can be useful!
