I'm observing that developers these days are quite surprised to see anyone write code for OpenGL / WebGL directly instead of using some layer of abstraction on top, such as Three.js or Unity etc. Few seem to know that OpenGL already is an abstraction of the computing model underneath.
A couple years ago I did some consulting for a company that needed a point cloud rendering engine. Luckily I had one ready to go. I showed them and they liked it and their young devs asked which library I was using. When I told them I used OpenGL they couldn't believe it. To them OpenGL was the "black magic box" and using it akin to having secret conversations with the GPU in some arcane cryptic language.
