Digital media at this point in time is more or less volatile from a historical perspective. It's best to consider it transient and have physical copies of the most precious things. Transient equals consumables - and companies leverage this. I have a few photographs from my great-grandparents from late 19th or early 20th century. Which are awesome. With physical media I can be pretty sure I can preserve data over the next hundred years (sans accidents). With digital media one still needs heavy redundancy to guarantee preservation. Not to think about the historical compatibility issue. Which storage format will be readable then? It's much easier on an institutional, internet archive scale to set up an ongoing process. I'm a software engineer and figuring out how to keep my digital data alive is a constant PITA...
