It's "just" art. Some folks like showing off their style via their homes, some their cars, some their bodies.
Most of the tattoos that I've seen are frankly uninspired. Dragons, flowers, skulls, knives. Some of the more unique ones are album artwork, but how creative is that really? Yet nobody seems bothered by this, they all show them off proudly! (There are some exceptions... My cousin had a full sleeve of Freddy Krueger making the pussy eating symbol with his blade fingers that was probably the crown jewel of some artists portfolio. An odd choice to be sure, but an impressive piece of work.)
I've come to believe that the draw here is the act of personalizing one's own body, not the quality of the art.
she's really into science and evolution in particular.
I don't think it's particularly pretty, but probably unique.
It doesn't matter if it's AI generated or not. Also these can be a great start to take to a real artist and then they can work off that if you want.
At the end of the day, if that's not a big part of it for other people then more power to them. AI generated at least ensures some level of image quality.
To me, it has all the charm of a brick.
For me, as someone with ~70% of my body covered, I would have no problem using AI-generated images as part of that input.
I'm not just going to get whatever the model spits out as a 1:1 tattoo. But when I have a hard to describe idea, having some references in my pocket to pull out and say "something sort of like this" is helpful.
Although I never understood tattoos. High cost, painful, and (in some circles) culturally looked down on. I just don't get the motivation.
