Bit shocked that there is so little love for the craft. When a artist hammers into his sculpture causing it to break, should he complain that marble isn't strong enough .. or get some more practice?
I think the big difference is how obscure the limitations are and an artist cannot evaluate it as simply as a when sculpting or painting. These constraints are not put on the creation process, but much later and this makes all the difference. When the artist has learned all the tools and starts experimenting, the limit is not what
can be creating, but what actually is actually
useable. It would be like saying to a painter that certain combinations of paint where not allowed, even though it would be perfectly possible for the painter to use them. Or for certain shapes to not be allowed by a sculptor, even though it was possible to create them.
I agree that it is a very worthwhile craft and interesting problem in keeping these techy constraints, but I fail to see how they can improve artistic qualities of the medium.
