Now that some of the files on my USB have been corrupted, I was thinking about information degradation and I came to realize that all of my favorite songs and movies would eventually fade away. No matter how many times you copy it onto a new device, a little is lost and that builds up over time (thousands of years perhaps). Is this how it works? Is it really the case that we can not preserve anything for very long periods of time, or is there a way?
