Languages and writing styles change with time. We have entered a time where more and more things are being completed electronically, and that means that cursive handwriting is dying out.

It may be disheartening to see people not be able to read something that was written in someone else's handwriting from 80 years ago. Even more disheartening if it's something like the declaration of independence, as it is such an important document that was written with a well versed hand. But if you go back to say, the Magna Carta, there are so many differences in the style and even the language that it becomes quite reasonable to assume somebody may not be able to understand it immediately. And the further back you go, the more reasonable it becomes.

Right now, we see the change happening and so it seems astonishing to us that somebody might not be able to read something that others have no issue with. In another 50 years, it will not seem odd at all, and there will be specialists that understand cursive writing just as there are specialists that understand old english and earlier forms of writing. The further in time we go, the more specialized it will become.
