As for your earlier point that disrupting Hollywood would mean replacing thousands of people with $30K jobs with hundreds with $150K jobs, that may very well be what happens. But the same argument could be made of any industry that gets infused technology or new ideas. Instead of taking such a reactionary approach and fighting to keep a seemingly dying industry alive just for the sake of the status quo, why not have a more productive discussion and think of real ways that the sometimes corrupt and, more importantly, no longer effective Hollywood model can be improved? Whether or not it comes from a trendy new YC-funded startup, it certainly seems like it's coming.
Personally, I find the idea of technological growth to the point of a "singularity" in the coming decades pretty compelling, and I think one of the biggest challenges we as a society will face is maintaining employment rates as technology continues to make things more and more efficient. Protecting those on the lower rungs in Hollywood and the music industry is certainly an important part of this.
