Please reread that section. You'll discover it has nothing to do with whether humans can pass the test.
If you can find a part of the paper in which Turing really does claim that it is unnecessary for most adult humans to be able to pass the test, by all means quote it. But this would be a surprising thing for him to claim, because it would undermine the entire foundation of his Imitation Game.
My original claim was that the Turing test needs to be passable by ~every adult human. You counterclaimed that Turing himself didn't think so, and provided that quote from the IG paper as evidence. But that quote is in a section about testing digital computers, not humans. Thus it is unconnected to your counterclaim.
I don't know how much simpler I can make it.
Find a quote that actually backs up your claim, or accept that you've learned something about the paper you told me to read.
