If it doesn’t get used for bad purposes it is very cool yes. So no it’s not cool at all. It’s fucked.

The resulting image must just basically look like a shadow, I can't imagine that they're going to get much internal detail with Wi-Fi considering that my router's signal practically gets blocked by a piece of cardboard.
This research essentially amounts to, humans can be individually identified with nothing more than low quality x-rays. Well yeah, so what, you can also use visible light and in any situation where you're going to use Wi-Fi to detect someone, it's got to be easier to buy a cheap CCTV camera.

I know people, funded, building WiFi scanners, but for the industry. They are cheap and can scan big stuff but they are quite imprecise, I wonder if you have like to stand in a specific pose on a specific spot for it to work?
