Generative art is ideal for this type of stock art use case where 90% is simply good enough for the vast majority of situations.
I feel like the gig economy (things like Fiverr) are unfortunately going to get absolutely crushed by generative art systems since most of their customers aren't that particular and are likely fine with anything that DALL-E / SD can pump out.
Predictably this is already happening, it doesn't take much browsing in categories such as tattoo design to spot the hallmarks of AI generated artwork. To add insult to injury they often pretend they aren't using AI, so they can up-charge for more intricate artwork that would take more effort if they weren't really just adding more synonyms for "detailed" to their Midjourney prompt.
Fiverr does have a dedicated category for AI art, but they don't seem to be making any effort whatsoever to keep AI art out of every other category, so it's pointless.
Why would the style be uniformized? It is neither observed to be happening with generative art, nor is it desired.
Which is kind of interesting. My first tattoo has its roots from it. Where I used ChatGPT together with DALL-e to express the concept I wanted on my body, and not a direct translation of it.
Worked out pretty well, got a lot easier to discuss how and what things would work and how to apply them.
It's wild that this is a thing when the tattoo artists job is literally to create the artwork for you
They're artists after all, not artisans.
