Skilled, but Naïve: The consequence of relying too much on mnemonesis and gnostic overlays to download distilled knowledge and skillsets.  They can, and will, grant you extraordinary, even superhuman, technical skill.  Excellence is guaranteed.  You will outperform any mediocrity, even any average professional you ever meet on raw talent alone, because you have been given a magnificent instrument.

But it’s the integration of the downloaded knowledge with your core self that lets you play it like a virtuoso, and there’s no artificial substitute for that.  Just experience and practice.
