The design does not ensure the preservation of content.

The internet started as an improvement on traditional libraries. Web pages could link to content anywhere else on the internet, which meant that content outside a certain web page would still be at users' fingertips. And people, including bad actors, can alter or delete the content they visit by following links. When someone changes the content behind a link, that’s “content drift.” When someone deletes it, that’s “link rot.”

Before today’s internet, the primary way to preserve something was to consign it to writing and that’s one of the reasons texts from thousands of years ago survived.
