The usage of generative AI has significantly lowered the barrier to entry for the creative industry, leading to an influx of AI generated products that are easily consumable and can be used to generate revenue.

Until the platforms begin to regulate AI art, which I don't see why they would, we can expect to see more of them in the near future.
