Personally I think Didier hit the nail on the head. No one is quite sure what shape the new industry will take, so they're speculating on new markets. I guess the philosophy is that if you don't put your chips down you can't win anything.
Marc, I've been doing art (Music, pictures,writing) all my life, sometimes paid, sometimes not. Earning money does not define art, however it does define whether your art can make you a living!
I guess most artists are sick of hearing that art it is to stimulate the mind, it's about time it stimulated the artists wallet!
Cheers
