I think artists are very cavalier about IP, on average. Many draw characters from franchises that do not allow such drawing, and often directly profit by selling those images. Do I think that's bad? No. (Unless it's copying the original drawing plagiaristically.) Is it odd that most of the people who profit in this way consider generative AI unethical copyright infringement? I think so.
I think hypocrisy on the issue is annoying. Either you think it's cool for LLMs to learn from code and text and images and videos or you don't think any of it is fine. tptacek should bite one bullet or the other.
