I don't think it is that long. Think of learning any spoken language. We expect that it takes AT LEAST ten years to be able to master it, and typically it takes much longer to meaningfully add to the compendium of literature. Usually we are talking about decades. It isn't just about the tool (speaking, writing) but being so fluent that you can successfully express yourself in a way that has impact. If you can do it in ten years with a software stack, I'd say that's pretty impressive.
