I can think of at least 3 reasons it will not play out. I may be proven wrong on all, but I’ll share them anyway.
Large companies will continue to control these technologies, and all are extremely risk averse. They will limit expression within safe bounds, and produce volumes of bland, inoffensive content. Over time, we’ll find it all boring and crave whatever is being censored.
Whatever we perceive as being produced automatically, we don’t value as much as what we know was difficult. Seeing a self-playing-piano and an accomplished pianist are vastly different experiences, though the music may be identical.
AI may become associated with manipulation and control, and provoke repulsion and disgust from humanity. We may relegate it to specific use cases with human-readable inputs and outputs.
