Or that they are from the same source, but one is more advanced than the other. Like a Telegraph and a Cell Phone.
(iirc MB has stated earlier that this presumption is testable)
Erm. Possibly? Why would a more advanced device transmit information in a completely different way (i.e. in Octal to base 8 rather than decimal?) Given my rudimentary knowledge of human psychology that to me would indicate that whatever is programming the devices is doing so from a different mathematical base (i.e they have 8 fingers / legs / appendages / tentacles) rather than 10. Like us.
