I'd say there's a big difference between an already accomplished artist broadening his horizons and someone starting out getting caught up in a certain way of doing things. A novice wouldn't have the insight or creative experience to say anything new working in a medium or style that has been exhausted by more accomplished artists decades before - this is generally why movements and mediums are abandoned. It takes the courage and great objectivity of an accomplished and mature artist to say, "right, I can tackle this" and begin to say something new in a medium.
Agree to disagree. Wish you the best in your artistic ventures.
