Agreed. It is an interesting article to read. The survey cited is also interesting in its own right [1]. We often forget that ideas we find trivial and intuitive are only so because it took the work of many more people and centuries to hone their ideas which at that time would be have been new and ambiguous. This is especially true with mathematics because a lot of the field focuses on getting the right abstractions to complex ideas which when done correctly seem "trivial, natural, and straightforward."
