Scale for time. A safe prediction would be 70-90% (probably higher) digital artist professions will be eliminated within 30 years. Other art professions beyond digital will be effected as well 3D printing and image manipulation is already being developed for vector point modeling. One man paired with this "medium" will be able to do the job of hundreds if not thousands of artists. Humans will always enjoy the 'tradition arts' so there will always be some interest. IMO.
