An idea that occurred to me a while ago:
If one knew the inner-workings of all the microcontrollers and computer electronics boards, wouldn't it be possible to write code that would produce EM or perhaps even scalar wave patterns that would affect reality as intended?
It would be a whole new level of hacking. Though, IMHO unreasonably complex. It would be a lot easier to design integrated circuits specifically for that purpose, instead of hacking the existing ones to "something similar".
