It's a piece of mind thing. Everywhere I worked did a lot of stuff on the background. The db is already so full on a normal Rails application that adding more reads doesn't make sense to me when Sidekiq works so well. You never have to worry about Sidekiq throughput, or when you do is to be careful to not overload the db because Sidekiq is so fast.

Rails is already on a slow language, I don't understand why we want to overload even more with slow things.
