Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively “see” and recognize individuals — even if they are not carrying a device and even if their phone is turned off.
There a couple open source repositories out there for setting something like this up, or at least the basic sensing. I started looking at it a bit but then got bored and didn’t try it out. You can set it up on a computer in your home (was gonna use a spare desktop I run Linux on), and the package had the ability to start to correlate movement skeletons as unique based on repeated motions. It freaked me out that it was theoretically possible to invasively spy on my neighbors on either side just by downloading some open source software… anyway I never went through trying to get it installed or working and it probably would have been a finicky setup, but the potentials for crazy surveillance are pretty huge with the wifi sensing, and outside of living in faraday cages not sure how much you could prevent it.

With the information it constructs and AI technology you could feed a photo of the neighbour into the AI and have it turn that information into real 3d environment with a real 3d model of the neighbour that actually looks like them.
Say 5 years ago I would have said: that’s nuts. But more and more these days I’m thinking, yeah having a house with some signal blocking might not be such a bad idea… not really feasible for most people, but you could integrate somewhat in new construction, and certainly you coild foil a room and use EM paint… but would be pretty weird.
Case anyone’s interested, couple of resources on SCIF wall construction:
