In 2000 the whole data hording apparatus hadn't been fully implemented yet, and AI surveillance was something more so seen as science fiction, nothing to worry about until possibly 2100. Sure there was some data collection but it wasn't like billions of people were walking around with surveillance tech in their pocket 24/7. Things have changed and drastically. Methods to monitor, model, predict, and control human behavior are now a thing and quite robust. If only people were aware of what's happening there would be a mass migration to secure hardware, OS's, comms, and of course not a single cloud based always on assistant in sight. IOT devices are cool when they are secure but they often get the least attention, few if any security updates. If you can get rid of robot vacuumes, smart home assistants, smart TVs, smart thermostats, switch to secure FOSS OS's on your computer and phone.
You can point a laser at someone's window and accurately record their keystrokes from the sound vibrations. Things go deep in the surveillance and intelligence world. Nothing is truly and absolutely secure, just more difficult to crack.
