Have you talked to the average 15 year old kid? Hell, have you talked to the average 50 year old? It will be the same as ever, a sea of absolute shit surrounding some true gems, be they from novel creativity or just excellent execution of well worn ground. The role of the trusted curator will rise and brands will gain more power.
I am sure I will watch MY 15 year old's attempts, and maybe a few from my extended circle but most of my consumed content will still come from what makes the cut to Netflix or HBO etc. Technology like this will empower the truly creatives once it has matured. I would expect closer to 20 years than 5 however.

Ah, I can see what's wrong there, just turn down shit randomness and increase the true gem sampling steps to proportionally increase the input weight of true gems and fix your output quality.
Basically - if it empowers creative people, their output will be fed back in and parameterised.
