I appreciate material's approach to replicating real world physics look. I'm curious though what other designs could be very productive even if they aren't intuitive out of the box and require some training to use them. Interfaces like the command line, APIs, text and even human languages require significant time to learn but they are worth the effort as they allow us to express an incredible range of concepts succinctly.
