You can't "defeat" AI. It's not an organization or a group to fight against; it's technological progress.
The weavers' uprisings didn't stop the Industrial Revolution either. AI is a tool, and those who learn to handle and adapt to it the fastest will be the ones who fare the best.
The weavers fought the capitalist system not industrial progress with the weaving machines being the easiest target as the where expensive to build, but highly profitable.
Same here: The goal is the overcoming of capitalism but until then we can annoy them by messing with their new toys.
It's not even a matter of bullying: NFTs disappeared because they were fundamentally not viable, and there's a good chance that generative AI is also not viable.
Generating an output is extremely computationally expensive, which is a problem because you need several attempts to get an acceptable output (at least in terms of images). This service can't stay free or cheap forever, and once it starts being expensive, that's also a problem in itself since generative AI is most suited to generate large amounts of low-profit content.
For example, earlier this month, Deviantart highlighted a creator that they claimed to be one of their highest earners; they made $25k "in less than a year", which is not much for the highest earner, and they did it by posting over NINE THOUSAND images in that time. They were selling exlusives for less than $10.
The only way this makes sense is if it's really cheap to generate that many images. Even a moderate price, multiplied by 9000, multiplied by the number of attempts each time, would have destroyed their already middling profit.
