PageRank and blockchain? :-p

  Eigenvector centrality has been around since at least the 70s, and idiocy is as old as humanity itself

    > Eigenvector centrality has been around since at least the 70s Yes, but the novel part is formulating the problem as such.

      Agreed that's kind of fair for pagerank though to qualify as a "big three" invention I'd be looking for more novelty
      • amelius 6y ago
        Yes. I wonder if Google even still uses pagerank. The true novelty, e.g. how to deal with SEO, is kept a secret.

  Blockchain I'd say definitely is one, but came or became obvious after the quote. So I think there are still another two. (Not sure about PageRank, it might be one of the two)

    Public key encryption? though diffie hellman was around in the 60s and public in the 70s
