Abstractions: interfaces as lists, details, and flows

I read a post recently of Dave Rupert lamenting that he can describe any digital interfaces as lists, details, or flows. This is, of course, an abstraction. Abstractions can be useful for reducing complexity and making things understandable. In code, they also can be used to reduce duplication and provide reason for limited responsibility, improving maintainability. But if everything is fit into a small number of buckets, it can certainly make it seem like there is a lack of diversity, a sameness to everything.

With any good abstraction, everything can fit into it with a certain level of mental effort. Some might be more willing to go further than others to make a given classification work. In code, too heavy abstraction can lead to a given abstraction trying to do too much, or conversely, functionality being limited to fit a simple concept of the abstraction.
