Anyone is free to draw a line in the sand to claim that my statements are hyperbole. I don't consider them so. When we read about China, the narrative of American Exceptionalism tells us that it is reasonable to think that China would seriously implement a social credit score but America would not. I think it is foolish to believe that kind of stuff. Let's just look at the facts.
We must ask how a social credit system would be useful to any government and wonder how any government would turn down the chance to obtain one. There is already hard evidence that the US Government wants to influence FB's news feed algorithm. Strictly speaking that is not a firewall, but the effect (censorship) is the same.
So feel free to belabor the difference between government meddling in the news feed algorithm to promote/demote various ideas and the technology known as China's great firewall. In my view that is a tangential and distracting discussion.
