It’s not a zero sum game, but there are not an infinite number of eyeballs looking nor is there an infinite supply of content at any given time. If the majority of “art” floating to the top is generated, it will change how people view the platform.

Maybe the AI “art” community being the first to thrive will mean actual artists get a bad first impression and avoid Lemmy. Maybe people do block it and it becomes a problem only visible to those who don’t already “get it” and just block.

There are many reasons why it could hurt the community. How do you fail to understand that?
