Generics are extremely powerful, but only if used correctly in your codebase. One reason why a lot of libraries are filled with Generics syntax is because it makes adopting their libraries very easy. Generics allow you to adopt your own types, and this means you are not tied to a specific typing system. I understand this code is probably confuse and hard to follow, but I tried my best to record today's lesson in a way that can be understood. Enjoy.
