…and some things (like MIS and what Shadow Rays are exactly) are (maybe) nice to know, but that knowledge is not only unnecessary for 3D artists, but even pretty useless (for most people).
In almost 12 years of using Blender, I have not needed it even once….
I actually tried to impress a girl at a party once, in 2017, with my knowledge of what a Shadow Ray is…but it didn’t have the desired effect: she was neither impressed nor amused.
