Technology develops at an alarmingly fast pace. What was state of the art even 10 years ago is considered ancient and obsolete by our current standards. Even though we may save information onto a hard drive, flash drive, etc., it doesn’t mean our children and grandchildren will be able to retrieve it and read it in the future.
As a court reporter, I have seen countless times where a company had been subpoenaed for correspondence and documents from as little as ten years ago, but they couldn't produce anything because the form in which they were saved is now obsolete.
I mean, really, how many of us would be able to open a document from a 5 1/4” floppy disk we had in the '80's, or even a 3 1/2” floppy disk from the early 2000's for that matter?
Today’s preferred way of communicating is via email, Skype, or texting, none of which is in a hard form that will be able to be retrieved 100 years from now.
That’s why handwritten correspondence should not only be encouraged, but a habit that each of us practice on a regular basis.
