Disagree. I think many people will actually be encouraged to try as the barrier to creating art has dropped and some of those people will decide to become more proficient at art.
Wow. I've pointed this out before - but this is just a TERRIBLE take.
Comparing systems like DALL-E 3 and Midjourney to modern illustration software is a fool's errand. Even with advanced graphic design tools like Photoshop you still have to employ the same artistic skills that have been handed down for generations: 3-point perspective, shading, basic poses, and sketching, etc.
If you can't draw, the fanciest graphic manipulation software isn't going be of much help to you.
As opposed to some doofus who has the ability to type in the words "3D", "trending on artstation", "hyper-realistic,", and "4K" and then proceed to churn out thousands of images in a single day. Stable diffusion is more like the equivalent of having your own personal artist on permanent retainer.
And photography initially had lower quality and performance ceilings compared to portraitists and artists of the day. And today, photographers win awards for their work.
New tools and techniques that lower the barrier to entry always get over used, over hyped and bring in masses of people making everything from impressive new things to absolute cheap garbage. And then people learn the limitations, the tools get better and a lot of people stop using the tools because they realize there are still skills that go into the process and they aren’t interested in learning those skills. The tools find their place, and new masters rise into the new world. And then a new tool is created and we start the process all over again.
