             | As an archive that supplements my personal archive, and the
             | archives of many others. Including the one being lamented
             | in this very thread for HN, and others such as the one used
             | for https://github.com/afiodorov/hn-search
             | 
             | The way to eliminate your comments would be to take over
             | world government, use your copy of the archives of the
             | entire internet in order to track down the people who most
             | likely have created their own copies, and to utilize
             | worldwide swat teams with trained searchers, forensics
             | experts and memory-sniffing dogs. When in doubt, just fire
             | missiles at the entire area. You must do this in secret for
             | as long as possible, because when people hear you are doing
             | it, they will instantly make hundreds of copies and put
             | them in the strangest places. You will have to shut down
             | the internet. When you are sure you have everything, delete
             | your copy. You still may have missed one.

           | Embeddings are encodings of shared abstract concepts
           | statistically inferred from many works or expressions of
           | thoughts possessed by all humans.
           | 
           | With text embeddings, we get a many-to-one, lossy map: many
           | possible texts ~ one vector that preserves some structure
           | about meaning and some structure about style, but not enough
           | to reconstruct the original in general, and there is no
           | principled way to say <<this vector is derived specifically
           | from that paragraph by authored by XYZ>>.
           | 
           | Does the encoded representation of the abstract concepts
           | represent the derivate work? If yes, then every statement
           | ever made by a human being represents the work derivative of
           | someone else's by virtue of learning how to speak in the
           | childhood - they create a derivative work of all prior
           | speakers.
           | 
           | Technically, the3re is a strong argument against treating
           | ordinary embedding vectors as derivative works, because:
           | 
           | - Embeddings are not uniquely reversible and, in general, it
           | is not possible reconstruct the original text from the
           | embedding;
           | 
           | - The embedding is one of an uncountable number of vectors in
           | a space where nearby points correspond to many different
           | possible sentences;
           | 
           | - Any individual vector is not meaningfully <<the same>> as
           | the original work in the way that a translation or an
           | adaptation is.
           | 
           | Please do note that this is the philosophical take and it
           | glosses over the _legally_ relevant differences between human
           | and machine learning as the legal question ultimately depends
           | on statutes, case law and policy choices that are still
           | evolving.
           | 
           | Where it gets more complicated.
           | 
           | If the embeddings model has been trained on a large number of
           | languages, it makes the cross-lingual search easily possible
           | by using an abstract search concept in any language that the
           | model has been trained on. The quality of such search results
           | across languages X, Y and Z will be directly proportional to
           | the scale and quality of the corpus of text that was used in
           | the model training in the said languages.
           | 
           | Therefore, I can search for <<the meaning of life>>[0] in
           | English and arrive at a highly relevant cluster of search
           | results written in different languages by different people at
           | different times, and the question becomes is <<what exactly
           | it has been statistically[1] derived from?>>.
           | 
           | [0] The cross-lingual search is what I did with my engineers
           | last year to our surprise and delight of how well it actually
           | worked.
           | 
           | [1] In the legal sense, if one can't trace a given vector
           | uniquely back to a specific underlying copyrighted
           | expression, and demonstrate substantial similarity of
