When you take this info and combine it with the ability of Wifi7 routers to "see" where people are in their house, you realize that the recent demo of Anduril's helmet that gives an information display that the soldier/cop wearing it can use to "see who is in the house" or "see around corners" etc. is not sci-fi but instead, something they can do today.
I hate that all our favorite sci-fi books were used as manuals for what to build next, instead of trying to avoid creating those futures in our real lives.
And yet here we are complaining that our phones are over-listening to us and our cars no longer have knobs.
