> About the only case where I can imagine "visual programming" being better than writing code is if you're trying to teach 3-5 y.o.

Visual programming is the way most people work in electronics and game industry.

I really enjoyed designing my own circuits, making parts into usable components for my toolbox and visually simulate its behavior.

Just like doing shaders is way more productive to visualize the intended effect doing it graphically than typing GLSL/HLSL code.
