Artists are always starving is because that’s how it’s always been. I don’t think it can be an argument for or against anything.
I’ve worked with ai image generation professionally and I can say that they are not missing new ideas if people using them aren’t. They are great for brainstorming new ideas. They can’t make a design, but are a great tool speeding up the process.
I love art. I go to galleries often. I don’t think ai can do that and will never be able to. Not true art like capturing a moment in time with the original style of the artist and their life experience. I don’t think ai is a threat to that.
