Thanks pier4r, Helix and EugeneNine for your insight on the fragile nature of digital media.

Some thoughts on the points you have raised:

I have read that the Chinese knew of many mathematical results often attributed to the Babylonians and Greeks, but that these discoveries where lost because the Chinese recorded them on paper, which does not last as long as the tablets the Babylonians used.

We have seen the recent loss of historical artifacts in the Middle East, from the looting of the museum in Baghdad to the destruction of monuments in places like Palmyra, Syria.

Some people have warned of the possibility of chips being cleared by a burst of extreme solar activity. Imagine the loss of information and resulting chaos that would cause?

Didn't NASA lose the original footage of the moon landing, and Lockheed lose vital information on the tooling for the F-35 fighter jet? Sounds hard to imagine, but the points you have raised show how this can happen.

With regards to movies and politics, the priority for films to appear to be "inclusive" and the fear of offending some group has severely limited creativity, with directors forced to follow the formula set by studios.
