Could we consider the mark/space contrast has being the "mark" of ink on the
white "space" of the paper?

Another consideration...
With morse, there are more than just two characters. There is a short tone
and a long one representing the did and the dah. There are also
corresponding short and long periods of silence which delineate letters and
words. Just try to teach a machine to read morse without taking these silent
periods into consideration!
