If you ask me, the Chinese Social Credit system is 100% fake.
While the technology for it may certainly exist, there is simply no reason why you would spend the money on such a system when you could just fake it and get the same results.
Those results being: the targeting, arrest and imprisonment of any dissident in China.
Now when anything negative happens to a Chinese it can be explained away by the concept of Social Credit.
Friend gets arrested for no reason?
>Social Credit
Didn't get the job?
>Social Credit
etc.
It's vaporware, astroterf, a meme.
It's just an elaborate excuse to justify any action against the public.
