I don't understand your question because obviously I am not. If you have a point why don't you make it. I am throttled on Hacker News so I won't be able to respond for awhile.
The discussion was about comparing GPT to a child. Since you're not a child, the assumption that you can beat it in Turing test is irrelevant, regardless of it (the assumption) being right.
The discussion was not about comparing GPT to a child. I started it so I should know. The discussion is about "having the mind" of a child. Sentience. I don't care if it can mimic Albert Einstein, I'll be impressed when I'm convinced it is Alert Einstein.
You are referring to other people, but they mean "mind of a child" in the sense it is as smart as a child, not that it literally thinks the same way children do. That's quite obvious.
