UVB-76 is a number station transmitting one-time pad encrypted messages. Old transport technology (radio) sending old, unbreakable crypto technology (one-time pad encrypted messages) at the speed of light all across the world. These technologies (as old as they are) will never be replaced with new infrastructure dependent technologies. The key is that they allow for decentralized, secure comms at the speed of light. No satellites or fiber required. It only takes a handful of guys to do it too. You can even run them from solar panels and battery packs from caves in Timbukto. Take that, nation state controlled Internet.

The Great FireWall of X, does not stop radio. Try to jam omni-directional NVIS. Better yet, try to locate the guys receiving it.

To be fair though, this is broadcasting, i.e. a one-way tech. It's also "decentralized" up to a point.

I see your point though. It's what I feel when I see 70-year-old cars still running: any car made after 2000 relies on electronics in a way that will make them unusable in a few years from now; but those old tin-boxes will still be around then and beyond.

There's open source computers for the important bits, the locomotion.

Of course the climate controls, radio and other stuff will eventually become useless with no direct replacement parts.

Until someone sends in a drone with a radio-seeking attachment on it and a few hundred pounds of high explosives strapped to its ass. It's hardly infrastructure-free when the infrastructure it relies on has just been blown to Hell.

The sentry gun is always going to re-aim faster, because it does not have to travel along as large a circumference to be at a different angle.

But antennas are neither difficult nor expensive to make. If it's destroyed another one can be erected within a day.
