Regarding computers and the internets:
1. Everything is connected to the internet. Refrigerators, traffic lights, mailboxes, lightbulbs... everything. And it all can be hacked and controlled remotely.
2. Hackers do not use mice or trackpads. They only use the keyboard, even when opening, moving and resizing windows in a GUI environment.
2a. Hackers only use LOUD keyboards. Even their laptop keyboards are buckling spring action so you can hear them go TAPYTAPYTAPYTAPY
3. Hackers are capable of accurately predicting anything. The trajectory of a car going over an open drawbridge, the food someone buys at a grocery store, which entrance someone will use at a shopping mall - ANYTHING. Because they have computers.
4. Any computer can be easily broken in to and controlled. Except for when you have a light plot and need to eat up time, in which case you have to physically break into a highly secure office building and do some technical thing to gain access. Hackers are good at doing that too. Because, you know, hackers.
5. Hackers can tell exactly what a program does by looking at a screen of hex code and random plaintext.
6. Hackers can pull signal out of noise floor in ANY SITUATION. Sharpening blurry photographs, pulling intelligible voice out of a noisy recording, un-deleting files, doesn't matter.
