Well, on the subject of pedantic, I stream a fair bit of my music over a frequency modulated signal transmitted in the electromagnetic spectrum. Most of my combined audio/visual streaming is on a hard connection between some sort of random access memory to an output device after appropriate signal processing.
Or, stepping the pedantry up a notch, I stream most of my video and text between approximately 400 nm and 650 nm in the EM spectrum and audio via molecular vibrational wave propagation between 50 Hz and 20,000 Hz - both of which use biological systems for final processing.
Definitions could help, but clarity begets pertinence - and who want's that?
... The "self" has been redefined to mean: A collection of molecules that you used to be, but are not now.
Indeed - you can't cross the same river twice (or exact aggregate quantum spin state).
No, as the series of court rulings have gone, the Fourth Amendment does not protect you from lawful search and seizure (such as a safe or hard drive). The combination to the safe, or encryption key to the drive, is not incriminating evidence and providing it to allow for lawful search and seizure does not violate your rights. They can admit evidence produced by oneself into court (such as two sets of books in one's own handwriting for a case of fraud) and that is not a violation of the Fourth (or Fifth) - just so with information one puts on a hard drive. What they can not compel one to do is testify against oneself (which is the Fifth by the way) nor assume guilt because you do not take the stand (not that a prosecutor won't toe that line with the jury). So, if one can keep all details of a crime in one's head and manage to destroy all other evidence which could be subject to lawful search and seizure - then you've got a shot at being a criminal mastermind.
I'm not sure I entirely agree with the line of thought - but I can certainly follow the logic as well as the precedence.
What would be interesting is if one's pass-code was material evidence with respect to the case - but a possible way around that would be limited immunity or ruling it as inadmissible evidence...It would make for an interesting case study.
