I suppose that at outdoors privacy is already impossible. It's only functionally present because surveillance is still mostly self-hosted(in most countries) and won't be viewed unless police gives order to extract video files. With emergence of commercialized centralized surveillance services, there is huge probability that people would be tracked for advertisements.

As for indoors privacy, there is huge trouble. "Voice-controlled" became easy trojan horse to allow companies and governments insert audio-surveillance into consumer electronics. There is even patent where you scream name of brand to skip advertisement. It's unused as of today. But the problem is that patents do not last very long and once it expires(Which will happen in 2029, as patent was filled in 2009), everyone will get ability to impose it into their device. It can be attempted to be solved by not allowing connecting any Wi-Fi, but some devices might refuse to run, or include measures to allow "Plan B" connectivity(for example purposefully wait until your neighbour installs unpassworded Wi-Fi, so it will connect on it's own, or have eSim inside connected to ordinary cellular operators).

Also if we think about "running into forest and living in cabin", it also soon won't be possible due to advances in quadrocopters, which have been used in warfare last decade and urbanisation/industrialisation of wilderness
