Well there were multiple ai's that existed in the 90's that could work out who was typing at the keyboard, one of them was about 1-2MB in size, the need for usernames and passwords is somewhat confusing when you know about that and other ai's! When you consider the level of surveillance that exists today with the mobile phone, smart tv's vehicle tracking, cctv, jobs on computers you can tell when someone is running late and you can probably even work out why. Even if you dont have a mobile and live in a rural location, as you walk around our bodies interfere with wifi signals, we block them, so you could use routers like a phased radar array detecting temporary signal weakness and other anomalies, plus any cctv that is installed can be used to pick you up as many might have seen with crime stories or Edward Snowden. I've had PTZ cctv hacked and I know of other companies with PTZ cctv have had their's hacked because they have spotted them moving around inside their office as they were not hidden behind darkened domes. I dont think people realise just how much surveillance there is today and the US Military have largely driven this at arms length, just like state assets have been ipo'd to keep them at arms length from the state. However when I have reported stuff to the police, its surprising how MS Windows suddenly doesnt work and makes it impossible to access your screen dumps, thats why you need a basic digital camera with no wifi or bluetooth to capture whats on screen because even cdr/dvdr's along with rw's will get wiped. I've even had my home accessed and old hard drives used as last resort backups wiped from a locked suitcase when on holiday one time and I only found that out weeks later. But that might be because it had allegations of Jeb Bush & other people rigging the elections in Florida for Bush to get a 2nd term in office. I dont know.
