Links are the backbone of the internet. Archive.org is a huge asset, but it relies on individuals being prescient enough to archive pages that might be lost to time. That's not scalable. Plenty of people will visit Wayback Machine to pull up an old page that's gone to the big 404 in the sky, but they won't actively submit links to archive themselves.

The bad design and low quality content is a symptom of the Internet's broken underlying economics. That's a human problem, not a tech problem.
