The author frames his post to be about education:

    please correct them for me. The misinformation has been around for 20 years

But his education will fail as soon as you're operating on more than scalars. It might in fact do more harm than good since it leads the uneducated to believe that mix is not the right tool to choose between two values.

If you only pass a boolean 0 or 1 for the “a” mix parameter, when is using mix better than a ternary? Can you give an example? I’m not sure mix is ever the right tool to choose between two values. It’s a great tool for blending two values, for linear interpolation when “a” is between 0 and 1. But if “a” is only 0 or 1, I don’t think mix will help you, and it could potentially hurt if the two values you mix are expensive function calls.

a can be a vector of booleans.
