I think this is a question of how much control the user is able to have over the end product. Music creation in particular is very difficult... I've produced music for 4-5 years, and the granularity with which one has to control the finest pieces is often mindblowingly frustrating. It takes years to develope a decent ear for mixing.

By giving up that control, you do get to a quality end result sooner, but that end result can only be an approximation to your original vision, since you're giving up the control required to shape the sound to that granular level.

Additionally, without the knowledge of how you got from A to B, you don't know what else is possible (or impossible.) In the process of doing something manually, you may stumble across a particular setting or effect that creates something you never even considered. And now, that is knowledge you can use on the next project.
