I guess it is good to be aware of what’s possible. But all this stuff about using WiFi to measure things about people—it’s a bit creepy, right? I mean, to state the obvious, we (as a society) have got a bunch of poorly patched or corporate controlled WiFi routers attached to the network. What a surveillance catastrophe waiting to happen.
I mean, heart rate? Do we have a giant network that can tell where everybody is and whether they are having a strong emotional response to anything?
