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).
