I agree with the actors but this article isn't great.
Actors, writers, and multimedia artists are all having their jobs threatened because of low-return, high-yield AI and generative products that do not have the ability to replicate human work and should not be utilized in order to do so.
If AI can't replicate human work then there wouldn't be a problem. If the AI were terrible, products made with it would be as well.
The entire fear is that AI can (or will soon be able to) do a decent job at these tasks.
