One takeaway from the discussion with @lizalinwsj and @joshchin : China’s tech model is a double edged sword, both at home and abroad. And the line between “digital utopia” and “digital police state” is quite often blurred. 🧵 In #Xinjiang, for example, surveillance is something to be feared - it allows police to track and detain people according to capricious standards; its presence imparts a sense of constant dread and fear on Uyghurs.
