It would have to have a pretty good model of my brain to help me make these decisions. Just as a random example, it will have to understand that an equation is a sort of thing that I’m likely to look up even if I understand the meaning of it, just to double check and get the particulars right. That’s an obvious example, I think there must be other examples that are less obvious.
Or that I’m looking up a data point that I already actually know, just because I want to provide a citation.
But, it could be interesting.
When I was a child we knew that the North Star consisted of five suns. Now we know that it is only three suns, and through them we can see another two background stars that are not gravitationally bound to the three suns of the Polaris system.
Maybe in my grandchildren lifetimes we'll know something else about the system.
Well we should first establish some sort of contract how to convey the "I feel that I actually understand this particular piece of information, so when confronted with it in the future, you can mark is as such". My lines of thought were more about a tutorial page that would present the same techniques as course you have finished a week prior, or news page reporting on an event you just read about on a different news site a minute before … stuff like this … so you wold potentially save the time skimming/reading/understanding only to realise there was no added value for you in that particular moment. Or while scrolling through a comment section, hide comment parts repeating the same remark, or joke.
Or (and this is actually doable absolutely without any "AI" at all):
(There is one page nearby that would be quite unusable for me, had I not a crude userscript aid for this particular purpose. But I can imagine having a digest about "What's new here?" / "Noteworthy responses?" would be way better.)For the "I need to cite this source", naturally, you would want the "verbatim" view without any amendments anyway. Also probably before sharing / directing someone to the resource, looking at the "true form" would be still pretty necessary.
