This is now my headcanon for why the UI of super advanced computers in 80’s sci-fi movies looks the way it does.
"8 bit 'looks' and hardware constitutes - and 'looks like' - some optimum as far as computing is concerned"
... so sufficiently advanced systems will look like it to interface with us as a sort of lingua franca.-
AGIs. Alien probes. The works. They will all look to us like a C64 or NES would :)
