You're not entitled to theft just because you're disabled. And that's what GenAI is. Even if you want to downplay the pollution and energy waste these models contribute to, you cannot ignore that every single currently available GenAI model is built from databases dominantly filled with stolen material. Terabytes upon terabytes of stolen art of all kinds.
It is a shame if someone's disabilities prevent them from creating art. The solution to that is not theft on a mass scale. I'm sorry your friend has crippling joint pain that prevents her from holding a pencil, but she's not entitled to anyone else's art and hard work.
There are disabled artists all over the world who create despite their disabilities, and they don't deserve to have their hard work and their pain invalidated and denigrated because you're under some weird belief that disability entitles someone to the title of "artist".
You can't just tell a theft machine to make a picture that kind of looks like the prompt you gave it and claim you're an artist. GenAI isn't a "tool". It's an attempt to discredit the ownership of art posted online so that rich people can steal from everyone and anyone, and every time you use that shit for your personal junk, you give that attitude and that concept more credence.
As a disabled person myself, this idea that we should be allowed to steal because we have struggles that may prevent us from creating art? That's what's ableist to me. The idea that well, I should just steal because there's no way I could ever make art the real way is offensive and tasteless to me. Esp since the argument isn't just that I should, but that I have a right to.
Also it's tasteless to hold up your disabled friends (who may or may not actually exist, as this is the Internet) to justify an argument for mass scale art theft....theft that, may I remind you, includes the work of hundreds of disabled artists who made their own damn art.
I agree that people should know the source material before they join a fandom. The fact that you tried to twist this into a pro-GenAI argument is pretty gnarly.
