Your quote does not back up your claim.

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.
