@Lady "and certainly, you privilege assistive technologies being able to read a thing over humans being able to read it"
Is the purpose of the assistive technology to help computers read text, or to help humans read it? If I were privileging the computers themselves over that of humans in that context, I would be saying things like 'Python is a language when on a computer but English isn't'. But that's not what I'm saying. What I'm privileging are significant functional differences for humans.
