How often do you find yourself writing or using `interface{}`? It’s littered all over the go code I’ve seen, including the standard library.

`interface{}` is the equivalent to using `Object` in java land. It completely punts on any sort of type safety, relying on the developer to handle messy edge cases correctly. I think one of the only reasons that it hasn’t been as severe a problem in go as java is thanks to that explicit error checking that go makes developers do (and that gets so much hate online), forcing developers to consider the case that the type isn’t what they assume.

But genetics provide a useful way to safely make those assumptions, and cut down on the boilerplate around them.
