I used to think the #echochamber within the US is bad enough, but compared to the gulf between what people within the #greatfirewallofchina (and those outside who read their news) think and the rest of the world, that's nothing.
It's rather worrying that we (humanity) go out of our way to create the post-modernist "truth is relative" outcome everyone claim to denounce. And that some Western leaders clearly want to ape the worst parts of information-starved autocracies, which will make it worse
Concrete example, just ask someone who reads mainland Chinese media what is actually happening in Hong Kong.
