I know there's something about USB A to USB A cables not existing in theory, but this would have been a good reason to have it exist, and USB C of course can do this
Also, Android to PC can sort of do it, and is arguably two computers in some form (but this was easier when Android still acted like a mass storage device). But e.g. two laptops can't do it with each other.
People would send me recordings from all over the world (e.g. on a ship in the Drake Passage showing enormous surges). It was a lot of fun, and I even got an educational grant to improve it.
Big bummer when Apple switched to solid-state drives (well, a bummer for my one small reason...)
