Content-addressing suffers the exact same problems, they are just a little more abstract. Actually, content-addressing already works pretty well. If you paste the SHA hash of a widely distributed file (e.g. an OS ISO or commonly used source package), you typically find many places to download the content. It's often more reliable then URIs for such kind of data. It is surprising that it already works well for the web, which was not built for CAS. Peer to peer CAS systems, such as IPFS make this much more usable. but then you'll probably end up bugging a lot of hosts that don't participate in that algorithm! ??? Trackers/DHTs were invented exactly to make this efficient and doable.

  Thanks for pointing this out, that's a nice idea!

  Interestingly there's some ambiguity about which document - is it the one that includes the hash, or is the hash inserted after it is computed?

> If you paste the SHA hash Okay, where are you pasting it? Wherever that is, it's a point of failure.

  But it's not a single point of failure, in contrast to most URLs. If Google dies tomorrow (unlikely), I will just paste it in some other search engine.
