No clunky wearables? No chest strap on the treadmill? Heart rate and respiration? Monitors everyone in the house simultaneously 24/7 on a cheap rpi? I hope this doesn't take years to come to market because this seems incredibly useful.

There are positive sci-fi use cases, but ONLY IF the data and automation are entirely under control of the human subjects, e.g. self-hosted home server, local GPUs, local LLM, offline voice recognition, private 3D imaging of home and human, etc.

Comcast renting out wifi hardware to all of their customers, and already bringing that technology to the masses should be concerning to you then.

Sensing is (sadly) already part of Wi-Fi 7. If you have a recent Intel, AMD or Qualcomm device from the past few years, it's likely physically capable of detecting human presence and/or activity (e.g. breathing rate, keystrokes, hand gestures). It can also be done with $20 ESP32 devices + OSS firmware. The open questions are on custody and legal usage of CSI measurements, not their existence.

But think of how much money they can make by selling your health data to insurance companies!

Yet another tool for our surveillance capitalism overlords to figure out when people are having sex.

Alexa: "I sounds like you're having sex. Would you like me to play Vivaldi's Concerto Grosso in D minor on Spotify and schedule a breakfast delivery through GrubHub?"
