Well there are two schools of thought on this one:

"Men can know more than their ancestors did if they start with a knowledge of what their ancestors had already learned....That is why a society can be progressive only if it conserves its traditions."
Walter Lippmann (1889 - 1974)

or

"History is more or less bunk. It's tradition. We don't want tradition. We want to live in the present and the only history that is worth a tinker's dam is the history we made today."
Henry Ford (1863 - 1947), Interview in Chicago Tribune, May 25th, 1916

My feeling is that the scoreboard is a visual tradition ,and of course we can get the positions on the radio or the computer, but why trash tradition if it is not hurting anyone?
Thank goodness the young guns are not in charge of cricket. Plenty of electronics and hi-tech there but you don't see it.

However we do have our memories.

"Even God cannot change the past."
Agathon (448 BC - 400 BC)
