I'm not sure if you're a web programmer or not, but all images, audio, and video on the web work by copying. When you navigate to a website that displays images/audio/video, this works because your browser is automatically downloading those files from the server to your computer, i.e. creating copies.
Importantly, this process is identical, whether it's a human browsing the web or GenAI browsing the web. It is 100% unavoidable for both humans and AI to download copies of media that their browsers come across on the internet. 100% of us end up with painting_photo.png on our computers. That's just how browsers work. And that download counts as legal under Fair Use in every single country.
Furthermore, once that download has occurred, we all have the legal right to observe these files, to learn from them, to peek into them however we want. There is no law that makes this illegal for humans, nor for GenAI. It is theoretically possible to make a GenAI that illegal makes additional copies of files that the browser has downloaded, but that's entirely unnecessary, as they could simply train on the already-downloaded copy.
You have two options:
1. Re-interpret current copyright law in a way that would make it illegal to look at files automatically downloaded when browsing the web. This would make GenAI training methods illegal, but would also make humans browsing the web illegal, since they are identical.
2. Add a new law to the books that would specifically target GenAI and make it illegal for it to do something that is not currently illegal or in violation of any laws. In this case, I would ask you: why on earth would you want to go out of your way to create this unnecessary law that the world is just fine without?
I can't think of any reason, except wanting to protect the business model of current artists. Which is lame, imo. We should not be outlawing useful new technologies to protect the profits of people in any industry, including artists.
