There is a tendency for markets to become oversaturated when too many use the same business model. I think this precedent applies to content creation as much as it does arbitrage trading or real estate. Porn is another good example of market oversaturation. Globally porn is a near $100 billion dollar industry. But the business model is so diluted and oversaturated only a tiny fraction of that amount becomes available. The porn industry might resemble the future of content creation in the distant future.

It is also possible enough will give up and quit content creation before attaining successful. For the business model to remain relatively unsaturated. Unlike porn content creation does have something resembling a learning curve to it. Without the instant gratification of porn. All of which could contribute to content creation not becoming as saturated.
