Me too. Listened to a podcast recently where they were talking about things like, "once you know what a monoid is, you start seeing them everywhere". I've tried to express these benefits to coworkers recently. Leveraging ideas from math allows you to take advantage of many decades of research and provides a structural foundation that's substantially more robust than things you might find in the gang of four book or other "design pattern" resources. I think there's still a lot of opportunity to bring these ideas to the masses in the way that Evan Czaplicki , the author of Elm, is trying to do. The challenge in doing so seems to be finding the right level of abstraction to expose people to with the goal of maximizing benefit while simultaneously minimizing the prerequisite knowledge you're requiring folks to take on to participate.
