Maybe this problems solves itself (at least) a little bit.
Before Node-Based systems (Houdini, Substance, Material Editors, …) Artists where basically separated from any logic-work. Scripting/Shader-Code was freightening and very different from the ususal art-workflow.
Now, artists get more and more into Node-Based systems because the entry-barrier is lower, less freightning and invites to experiement - which brings them a bit nearer to logic-work and with that a bit nearer to the technical side of things.
Maybe because of this, we’ll see more artist with a passion for technical things because the transition is softer now.
Actually I can see that at the school where I’m teaching a bit: Since Unity added a Node-Based Material Editor the projects make use of custom materials way more often then before! The artists get curious and try around while before, writing shader code was an intimidating barrier.
