I wouldn't be so sure about that.
The overwhelming majority don't make big money, but many, many creatives make a living on their art, and a lot of them are OK with being fairly low-paid (I know quite a few). They do what they love, and get paid enough to keep doing it. As a musician friend of mine says "You know what's great? I get to play music for people, and then they pay me for it, when I'm done!". He is not a huge rock star, but does well enough to tour around the country.
People tend to sneer at creatives, thinking of them as "parasites," or "doing something that anyone can do, so why should they be paid?"
I can tell you that I appreciate having a trained professional designer, help me with my software design. They can do something like fart out a logo in five minutes, that can become one of the most significant assets a company has. That's a really valuable skill.
We'll have to see if AI can actually replace that. It probably will, for many contexts. It's gotta be better than some of the efforts I see, by engineers that think they are creative, but aren't.
Actually, that's what I do, these days. Take a gander at my work. It's not exactly "Hobby grade" stuff, but I don't make a dime from it.
I'm grateful for the many years of being a professional, that helped make it possible for me to do it creatively, these days.
This transaction does not need IP protection at all.
That’s going away. Now it’s becoming a lot more like professional sports: either you make it, or your hard earned skills are useless on the job market. It increases the risk significantly and will lead to less people pursuing a musician career.
I hope that my explanation is not perceived as judging in any way, but purely as an explanation.
I think uncommon focus, discipline, physical and mental dexterity along with the ability to perform under pressure are being undervalued here.
I've discovered breakthrough algos and delivered solutions which personalize medical care, sometimes with life and death outcomes.
Yet somehow that doesn't count when the company wants someone who has done personalization for consumer products.
I have other examples from other common DS roles/tasks, where I have done the equivalent thing to that role in a different context. And somehow that never seems to count.
So no, I don't have strong evidence that the job market values generic skills. Perhaps your experience has been different?
I can also hear someone saying "with the attitude that the poster is taking, I'm not surprised"-- so let me point out how difficult it is to extract attitude from text, and that the context here (presenting evidence to refute a claim) is very different from an interview context.
Your skills are cause you wanted to do it, not because you wanted to be famous. That's the by-product.
