I agree with those who say that painters, photograpers, printers and web designer are still there even after their job has been demistify and became accessible for a large part of the non specialist people. It happens because their tools got easy to learn and very automated.
it's a question of time that our 3d Software change to become so simple that anyone could render a good image in a matter of hour after using a 3D package for the first time.
when this arrives it will not stop me to continue learning new 3D Technics and try to make renders that will amaze my clients, at least i can try to do so.
But the true is that it will change so much the cgi industry that i will have a lot of problems trying to explain my clients why he should continue to give me thousands of dollars for my work, when he could do almost the same himself or his eleven year girl.
As a open and technophile person i will probably be using right from the beginning this hypothetic new revolutionary software, this will be good for my amusement but for my money i will have to find a different business model.
so the only real questions are :
how can we in the cgi industry change to continue making money with our knowledge ?
on this i really have no idea for the moments, but there are some ideas like moving to 3d printers, augmented reality, stereoscopy and other emerging new technology.
And how many time do we have til we can't make any more business the way we do ?
i would say maybe an other 1,5 to 3 years maximum
