> Line of sight free space optics can be immune to many many forms of jamming The most powerful weapons on earth already are immune to jamming. ICBMs use celestial navigation (pictures of the stars) to course-correct, which is a form of navigation you cannot jam.

This form of navigation is probably only accurate enough for nuclear weapons, you’re not going to get meter-Range CEPs with that. You probably have to select a city you want to hit.

Quantum navigation is likely to be more precise.

That's the interesting paradox of technological development. If it's out of the bag, then it's out of bag, but that cuts both ways. You can never control who will gain access to advancements. Even if you trust the custodians now, you don't know who they will be in the future, &c. Eventually you end up at a fork: either pursue and endless technological arms race or find some way to build lasting cooperative and peacef…

You cannot control, but you can backdoor

Shoot a laser pointer at the receiver and there's a good chance you have jammed the thing.

how do you detect/find the receiver? thats seems to be a problem

I thought comms was two way.

This is a very good read on the state of the art when it comes to submarine-launched missile accuracy, which are presently inertially guided with a stellar update during flight. https://thebulletin.org/2017/03/how-us-nuclear-force-moderni...

Thanks for the link, very interesting. So CEP is estimated to be around 100m. Better than I thought but I wouldn’t call it hitting a specific house yet.

What do you consider the primary benefit of pinpointing a particular house in nuclear war?

Big tech deserves to burn for their evolution in naming alone.

Bmw would like a word: BMW M760Li xDrive V12 Final Edition

And also squatting on the i3 name because one of these is not like the other https://duckduckgo.com/?q=bmw+i3+2020&iax=images&ia=images vs https://duckduckgo.com/?q=bmw+i3+edrive+35l&iax=images&ia=im...

I mean, seriously, there are more numbers available

> Line of sight free space optics can be immune to many many forms of jamming. I’m a bit of two minds about this. Obviously jamming resistant high bandwidth communication enables some scarry possibilities. But the lack of it is what drives and will drive militaries around the world to put more and more autonomy into weapons. It doesn’t matter what kind of treaties we write on paper to prohibit technologies. During a…

I got seriously terrified by reading a PKD SF story at 15 about the few surviving humans hiding from war drones still hunting people long after the war had ended.
