I see the point you're making, but I have to disagree. I think a part of mastering any area of expertise is being so good at what it is you do that it becomes second-nature to you. This allows you to use your skills on demand when you need it, whenever and wherever. No prep required. And since it's second nature, you can tweak it as needed to make it fresh and interesting to yourself and other people.
A good example of this musically is Lady Gaga. She has performed the same set of songs so many times, but she has mastered her musical ability and skills so well that she uses it to her advantage (and the audience's) in a performance.
She improvises on the spot, harmonizing lyrics with herself and backup singers, changing lyrics to make them relevant to the crowd or show she's doing, and if she's on a piano sometimes changes up an entire song and adds parts to it which never existed, and may never exist again.
The result is an engaging performance that is never the same a second time around, and it leaves a lasting impression on the audience.
This is because Lady Gaga is actually an artist, with practiced skills and true talent, vs. a performer that has to be auto-tuned when on stage because they were picked due to their looks or marketability and not due to any inherent talent.
That's what we still SELL as the ideal of art and music, but very rarely deliver. LG is a refreshing presence in modern music.
