It occurred to me as I was looking through one of the indie filmmaking books that I have that describes super 8 and 16mm, along with the editing process by splicing, that I was wondering whether outdated technology in a particular field may need to be learned at all?
Speaking beyond the scope of purely academic studies.
All things considered, if you are ready to learn the current useful technologies and go out there and start using them, you will not be required to familiarize yourself with previous iterations of those technologies. Consider the example of a computer. The maintenance of automobiles. The medical field. Navigation.
While maybe there is no need to learn these things, I believe it may prove beneficial to have some knowledge of them.
