Which one was designed for streaming audio again?
Sorry, I keep forgetting.

My post listed four technologies. Of the four, only I2S was originally designed for streaming audio.

From your original post: "I2S is engineered for communication within a box, especially on a circuit board"
How is "on a circuit board" helpful for streaming audio? Or do you suggest that audio only be 'streamed' on a circuit board?
The audio streams from place A to place B. This can be from one part of a chip to another, from one part of a circuit board to another, from one circuit board in a box to another, from one box in a room to another, from one room in a building to another, from one campus to another, etc...

USB is engineered for lowest possible cost over short distances with control from a central point.
Perhaps more accurate to say USB is typically engineered for lowest possible cost . . .

Well, yes and no. IIRC, USB had, for technically sound reasons, a separate Audio class, if not from the off, then very soon after.
Some argue that I2S was never really designed, just cobbled together as a temporary fix but that it sort of stuck around.

And was (at least initially) only aimed at on-board chip-chip communication. i.e. no ESD protection required.
