the internal mechanism of how a computer does it seems like
mere trivia/jargon rather than anything fundamentally
important to intelligence. A computer may have reading
comprehension without having it in exactly the same way that
a human does.
Yes, it is trivia what we decide to call it, and computers may someday have "intelligence" or "sentience" without having it in the same way that we do. However I think mechanically structuring data and building a querying tool over that cannot be considered "intelligence" or "comprehension" in the sense we seem to speak of here.
since it's pretty clear computers can handle the
"informational retrieval" side of reading, we should now be
focused on generating a "world model" based on text.
Yes, that's what Google's working on with Knowledge Graph. It's quite good, it's integrated with search already.
