I don't want to have to remember the properties of every object, or the arguments to every function, or a myriad of other things. I could be using that time and energy to work on other things that are more important.

It's not about knowing the interface to a blackbox. It's about semantics. It's about knowing what an object or function is doing.

As a developer, it's your job to know how your code works. There really isn't anything more important than that.
