You know, based on some people in China has learned building VPN/proxies, the best and cheap way to communicate under surveillance/censorship is to hide it in plain sight. In fact, that's how most these proxy software works.
So no, you don't need sci-fi technology. If you really want to communicate, context-coherent code words though bugged phone line should be enough, at least enough to arrange a meet up.
Also a interesting thought: maybe one day when human invented a device that could listen to quantum communications, we turn it on and ended up detecting a sea of encrypted conversations from another space-time perhaps even an universe just aligned with ours, and the device also experiences unexplained packet loss. That's what I call a plot of a sci-fi story :)
If you are at a stage of "we shoot people on suspicion of them being against The Cause" then indeed, this will not help.
Still, if you are not at that stage, doing something is better than nothing.
Don't get me wrong, an uncensorable and free internet for everyone is something I am very much for, but when we start to talk about nations limiting access while information has to flow, the question is not about mass-adoption anymore, but rather seeing the right tools reaching the right people.
A good example of this, imho, is the situation in Iran, when they cut off the internet. Some people were able to help themselves thanks to VPN-like apps and outside help, but that is not the majority of people.
But as the world is now, it's not feasible in any sense yet.
The current internet is the best we have and it >can< work, we have to find solutions inside the current possibilities until tech is advanced, cheap and accessible enough for everyone interested to easily host their own infra.
But this is not easy, because what is the real goal... really?
It feels like most of the internet is about making money or involving money, even from the end users. Is there even something to fix when most people don't care enough to ditch knowingly harmful products like Facebook, TikTok, etc?
But I generally think that trying to solve social problems with technology is a futile endeavor. Someone will always have violence on their side. And violence is the ultimate weakness.
but in the scifi mindset, what if you have an entangled ram bank with someone else. i write to mine and they can read it from theirs. that could create a sort of entangled ram bank mesh network network? (i know, maybe super stupid thought.)
this got downvoted, ofc because i know nothing.
Glad some people do like to be smart rather than smug, and provide the link :)
The next time its foggy or raining a tuned photon sensor to the spectrum that these devices run at will light up like a Christmas tree. If you're really intent on catching said people, you'd have drones flying around sprinkling light chaff and detecting where it detects optical scattering.
