It’s wild that anyone who cares at all about artists and writers of any kind would support this tech.
I absolutely support this tech.
That there are crappy people out there that screw people over is not a new thing introduced by this tech. Are some people going to lose their job over this tech? Absolutely! That matters greatly to those individuals that lose their jobs, as it does every individual that loses their job. Will it replace all writers and artists? Hell no! It's a tool, tools allow you to do more with less, this is no exception. Jobs tend to require you to keep up and become proficient with modern tools, if you can't, you're screwed! But that is a 'you' problem. This happened when the computer was introduced to the workforce, the Internet, the search engine, etc.
If you get paid 40% less because they expect you to do 40% less work, you do 40% less work. #1 you either left a big hole in you contract or #2 you have no interest in keeping your client to it's contractual obligations. If you're running a business (writing) and you have either or both these issues, it's not the problem of AI that you're loosing your job... That might seem harsh, but too many people have no business running a business. And having specific job xyz isn't a right, it's a necessity and/or a privilege, if your job isn't needed anymore, why keep it artificially intact? That sounds like a very conservative point of view...
What I'm seeing, again and again, with new tech is that certain types of managers/decision-makers have hasty conclusions based on tech that they don't understand and their company haven't actually tested the use-case for their particular niche. I've been in IT for a long time, I've been making my own position obsolete for over 25 years and I've also been let go at times when I wasn't done making my position obsolete yet. What happens is after six months they call you if you could please help fix their issues again for the next couple of months. Sure, no problem! This is my new (higher) rate. Why is it higher then six months ago? I've more experience, learned new things, and my skills have become more in demand...

After 25 years I'm still in IT, but I'm not doing the same thing in the same way as 25 years ago, not 10 years ago or even 2 years ago. Why would writers/artists be any different? Are manuscripts still handwritten? Or typed on a typewriter? Sure, maybe a few do, but most companies will not work with generic writer/artist who still handwrites the manuscript, unless he/she/them is a star. Anne E. Johnson is not a star.
Imho this tech is only as good as the people using it. If it's not old writers/artists using it, then new writers/artists
will use it!
Do I care about artists and writers? No, not really. It's like saying, do I care about humans? Not really, most are crappy and I don't know all of them. Do I care about some artist and writers, maybe. But I'm also a realist that says, if you can't hack it in your chosen profession, maybe you shouldn't be in it...
