That's not empowering a guitarist to play guitar in some new or better or more efficient way.

Drum machines and VSTs are tools for any composer to synthesize a composition. They solve a different problem for a different set of people that can include but is not limited to guitarists. And as you pointed out they predate AI.

How do drum machines and VSTs make you better at playing guitar, or allow you to do that more efficiently or for higher pay? How will AI do that?
