a common affordance in scifi is that spaceships can just video call each other, even spaceships of different races who have never met before. this implies that there is a sufficiently mathematically obvious RTC protocol that all spacefaring races eventually discover
„but halcy, the computer simply adapts the signal“ try piping an opus bitstream into chatgpt, see how that goes
„This situation where everyone uses their own protocol is ridiculous.“, says Alien A, „We shall develop one protocol that satisfies everyones ne-“ and before they can even finish, they are handed The Document. No one remembers where it came from originally, what the letters „XKCD“ mean, or the significance of the number 927
Thomas Tuegel@halcy Just the idea of _having_ a protocol presumes that the various species have compatible visual perception. A human video stream isn’t going to make to a species that isn’t using RGB-sensitive receptors, no matter how it’s encoded.
