Umm... You've seen NSA's data centers?

"No way every domestic telephone call is being recorded and transcribed!"

Next moment:

"Woah! Gnarly dude! A.I. that's been trained on ludicrously large datasets! It can mimic your mom's voice, dude! Here, check it out! It can also write e-mails like a human!"

All the leaked intel points to: this is a very real and possible situation. Better not think about it and stick your head deeper into the sands.

On a technical level Google knows where 80% of Americans are, because they're using Google's Android. It could report back what cell-tower their mobile-computer is using, or it could be using the mobile-computer's GPS, or it could take the SSID of any nearby WiFi or Bluetooth device and compare it to a map that's diligently updated daily by every Google Android user. To say Google knows where every Google Android user is is very technically possible. It's also technically possible to infer other things with a satisfactory probability, like where the other 20% are.

The NSA, CIA and FBI were the data harvesters. The solutions to their needs were financed by them and we got... for instance, Google. They had vasts amounts of data and needed a way to search through it. Likewise the intelligence-agencies wanted ways to impersonate others digitally and... oh look, we have live 'deep-fakes'. I won't bother espousing how the economy serves the state's needs first and any consumer commodities are second- or third-order artifacts, but really? You don't think the very thing advertisers are doing now--in no way secretly either--are not technically feasible for the rapacious, infinite-money pits of the secret-police?

Right--I forgot! Only communists have secret-police!
