It really depends on what ypu are dealing with - if you are worried about communication being too centralized and monopolized, it might be a good idea to start building and alternative. Doing that might avoid the situation getting worse, slow it down or even reverse the trend.

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.

> sci-fi technology

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 :)

It's possible that any such technology would be too complicated to ensure a clean supply chain or have weaknesses that would allow it to be tracked or jammed. Real devices have some kind of engineering tradeoff.

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.

i like this idea. it does sound scifi, maybe quantum entanglement? i know nothing about this stuff tho :)

Or, hear me out, optical laser mesh
