My take is that you can train AI on whatever you want for research purposes, but if you brazenly distribute models trained on other people’s content, you should be liable for theft, especially if you are profiting off of it.
Just because AI has so much potential doesn’t mean we should be reckless and abusive with it. Just because we can build a plagiarism machine capable of reproducing facsimiles of humanity doesn’t mean that how we are building that is ethical or legal.
