Things that are important to society will naturally be preserved. I believe in the moral right to be forgotten.

We cannot, and should not, preserve all of knowledge forever.

Don't get me wrong, I love the internet archive, and the team behind it are incredible. As a resource it's very important to maintain and preserve. However, I'm sure that at some point, either due to the economics of it or through hardware failure, the content saved by the AI will begin to be lost. I don't see that as a bad thing.
