So Bionic reading is just a form of speed reading?
And it turns out that comprehension is suffering from trying to read faster... I think that most people, when they read, do a sort of automatic "speed reading" in their mind already.
What I mean is: I notice that when I read, my eyes will skip parts of words where I don't need to see all the letters to know what word it is. What if all this trickery simply hinders our innate and built-in "automatic speed reading" capability?
