This is a hundredth time in history when technology progressed and artists had to learn new ways to make money. I've learned art in art school - none of the jobs that my art teachers had in their youth are relevant right now. The tools, the pricing, the workflow, the clients requests and expectations are all different. You can keep some of the skill, but you still need to learn and adapt to the new reality. Sometimes it takes 5, sometimes 15 years, but the job of the artist is always transforming.

The illustrator from the article is probably drawing in Procreate with an Ipad. Probably doing her promotion on social media and doing business with her clients remotely. All of those are recent technological advancements that appeared in her lifetime and completely outperformed the previous way to do commercial illustration. Illustrators that worked before that had to learn those new ways, or lose their jobs. This happened dozens of time in history. Now is the turn for current illustrators to adapt.
