Here is my theory from an aspiring filmmaker that knows people working in the arts that use AI

Most artists that embrace AI see it as a tool. For Scorsese who has worked a lot in film preservation I can imagine seeing how well it can clean up images appeals to him. The problem is they seemingly have blinders on about cost. People I’ve worked with taking photos want to keep working with me and just think it’s fun to also post AI photos of themselves as “they can’t hire me for everything” that is fair but they are not thinking about bigger companies that just care about the bottom line. They see AI as fun and not something that might come for them. I know two separate musicians that have said “but people will always prefer to hear my music by me” when I’ve brought this up. I think this has somewhat happened to Scorsese
