The most natural implementation of any feature request is additive, attempting to leave all other elements of the design in place and simply inserting one new component: a new button in a UI or a new parameter to a function. As this process is repeated, the simplicity of a system is lost and complexity takes its place. This pattern is often particu... See more

It’s easier to hedge against uncertainty, entertain multiple paths, and dilute your focus than to develop a strong opinion about what to exclude.
