Is there technical reason to believe that shadowsocks or similar technology is the last stand against automated censorship?
I would just say this is just yet another stage in the censorship/anti-censorship cycle.
There's no guarantee that "the censorship arms race" will continue, even in your specific nation-state.
For example, I bet there's not much anti-censorship software being developed in North-Korea, because people don't want themselves and their entire families tortured to death.
The real problem here is not that we might be lagging behind governments with our anti-censorship tools. The real problem is the existence of governments to begin with, because as long as they do, they will want to control their subjects as closely as possible.
Policitians and the real rulers behind the scenes are all psychopaths.
They see us as human livestock, and any one of them would be perfectly happy with a global North-Korea, as long as they personally would be in the tiny ruling elite, with all the riches and power a psycho could ever dream of.
