Re: It's in its infancy, but it will improve
* You have a personal tracing device in your pocket RIGHT NOW (your phone).
With as much tracking turned off as I can, and if I was worried that people were actively tracking me with it, I'd leave it at home.
* You have listening devices in your home RIGHT NOW (Smart TV, digital assistant, games console...)
None of those. A few things have microphones and internet connections but I've set them up and know what they're doing. If I was worried that people were actively tracking me with them, I'd disconnect either the microphone or the connection.
* You have behaviour monitoring devices RIGHT NOW (activity tracker, internet connect fridge, home automation...)
None of those at the moment, but I once had an activity tracker that I gave away because I didn't use it. It monitored my heart rate during exercise, and could send it to my phone but I never enabled that. So it was a tracker whose tracking data only went to me, and it lacked the technical ability to report on me. If I was worried that people were actively tracking me with it, somehow circumventing the limitations of the device making this impossible, I'd leave it behind.
* You are using facial recognition RIGHT NOW (Facebook, Windows, Apple...)
None of those. I prefer passwords to log into my computer, and no Facebook account. If I did use a facial recognition system, I'd do so in such a way that the recognition was done using local processing on local data only.
* You are happy to be tracked RIGHT NOW (advertising)
I am not happy. That's why I have ad blockers, tracker blockers, and a DNS filter. Even that is tracking for economic purposes, not complete surveillance, so is not as bad an abuse as what has been considered (and done already) by governments.
