Doubtful it will hurt the real craftsmen. It may however hurt the third world sweat shops that pump out cheap imitation stuff. When a person wants a hand carved solid wood desk, they want a REAL wood desk. While you could get a similar looking object, we're not going to get the actual materials. As anyone who's ever heard a Stradivarius, versus a similar violin, it's the materials that make the difference. Heck even in modern musical instruments. Fender American guitars sound better than the cheap POS that you get from Indonesia(not sure where they are made). Until it gets to the point where you can actually create something with exacting materials, you'll always have craftsmen.
This might make some people obsolete. But not all craftsmen.
