I suppose that's the internet itself...
I agree. Permanence should be tied to individual wills, not collective inertia. If you want a permanent thing, work for it, host it and publicize it
So much of the past is completely opaque to us because of decay, intentional destruction and lack of interest. I think there's a moral imperative to preserve.
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.
Decay is natural, but so is the human/animal urge to stop it.
