It’s a perfect storm, really:
At the start, AI is attracting a lot of customers, which can freely or cheaply generate images, music, and 3D models. They become “addicted” to their own "creations," making them less likely to interact with original content. They don’t realize this problem but push this slop onto the regular markets, diluting them and turning away customers.
We saw the appearance of large buyer entities on Turbosquid and CGTrader. These companies buy up all the models in order to train 3D AI models, that will degrade the entire market even more.
Next, Epic bought Sketchfab and Artstation, both very respected sites, with very good markets. After the takeover, the Sketchfab marketplace was assimilated, and Artstation was left for dead in the gutter. This causes resentment in buyers. Not only for Epic (FAB) but also for the marketplace as a whole.
And lastly, the reaction of governments worldwide: Instead of supporting artists in these challenging times, the focus is somehow shifted to oil, land, and fostering the rich (in particular, AI).
The solution? Purging AI from the marketplace, abolishing the credit boost system, and going back to organic search results based on buyer satisfaction will change nothing. It is simply too late, and we cannot go back. The key is finding a niche and growing from there.
Big things have small beginnings.
