Wow, ok then. What I love about the quote is the notion that a practitioner who is "great" can do something that no one has ever done before while acknowledging that you can be "good" with just the skills to re-do what has been done before.

I do separate in my mind engineers that can take a blank sheet of paper and create something completely new, and engineers can really only start from something that already is, or a close to what they want, and morph it into something else.
