Because it's likely to replace at least a portion of the talent needed for creating art. AI is going to do a lot of the heavy lifting, and "manual" art will be a specialty. Artists will still be needed, but the AI tools will drastically change entire industries... less artists will be needed, and the few talented ones left will be training models to sell for everyone else. Programming has higher stakes than art, and requires more "correctness", so it's likely to take much longer for AI to properly replace programmers. Even then, programmers would just switch to AI engineering, which by then will be needed everywhere.
