#3Rule of thumb is never having sensitive conversations where such exploits are feasible.

Thinking atomic bombs :(

With enough processing power, you can listen to anyone as long as you can get an object in frame that’s vibrating with speech (the UK and Chinese CCTV networks comes to mind). Depending on resolution, I’d expect this to be the case for any footage already stored. It’s just a matter of having a distributed computing job kicked off to comb through video data and add the additional audio metadata.
Will you only speak of sensitive subjects in rooms with no windows? Will we be silent in public? These are issues where technology, politics, and human rights intersect.

#6Ah, yes, I saw this in 2010. They didn't have high enough resolution to detect actual vibrations, so they used an algorithm based on per-pixel color shifts. Really clever.

#7Now imagine doing this with a high res satellite anywhere on earth.

The same ones which have prevented large scale open military conflicts involving superpowers for the last 60+ years? Atom bombs have likely saved more lives than they have taken, if we had conventional wars with modern technology without MAD.

That’s one read on history. Another is that the world has been tremendously lucky to not have suffered a nuclear holocaust since WWII. Many powerful people have done everything they could to advocate for nuclear bombings in the past 60 years, and we’ve had some extremely close calls with near accidental launches.

That is exactly why almost all DOD secure areas are windowless.
