How to write like Cats

For many Scala programmers the Typelevel Cats library is essential. It is an extensive grab-bag of useful functionality. However, several Scala developers tell me they don't use it because it's unnecessary and overly complicated. I hope to dispel this by introducing the benefits of a core pattern Cats employs, the type class. 
 
We'll live-code our way from classic subtype polymorphism to ad-hoc polymorphism Scala style. Then we'll get rid of all that code and replace it with a few lines of Cats to show how easy and useful it can be.
