I can appreciate your opinion on this but it strikes me as a bit of a 'high horse' statement to declare that copy and paste is the wrong way to learn or advance the process of mental reasoning. At some level, we're all copying someone who came before us, unless you're working at the absolute bleeding edge.

Everybody has their own style of learning, and not everyone is at a point in their journey where poring over API docs or dropping down into a lower level makes sense for them.
