More to the point, we (big assumption) advocate laziness for the sake of efficiency and speed.

If one asks "How do I do this?" , then the reply will include directing the one who asked to a module if it seems to be a solution. Modules were written to make our lives easier. Nobody discourages one from making their own solution to understand how things work.

Remember though, you don't have to know the inner workings of an interface / module in order to use it. Just read the documentation and look at some examples to see if it's what you need.
