What you are suggesting are macrostock style edited premium collections, which exist but people dont like paying for

Otherwise microstock is the world of mostly amateur content.
Before ai, the camera only content was pretty ghastly if you search by newest.
It was not high end premium content from professional photographers.
I am sure Adobe has done the math and fresh ai with good lighting and composition looks a lot better than the amateur photo snap shots.
If ai was selling badly they would not accept it. They take 5 million a week and have tripled their inspection team. So ai content must be immensly valuable for them.
I doubt the issue is as big ad the artickes make it out to be, otherwise there would be a huge move of customers to ss or istock.
And adobe would greatly limit ai uploads.
If they are not doing that it is because they are making money.
All agencies could benefit from more edited collections, maybe a middle tier version.
The question is will customers be ready to pay for this service?
Probably notbut whoever wants to can choose to buy macrostock whenever they like.
