This isn't exactly new, and perhaps I wrote about it in the past, but writing about chatgpt motivates me to write about it again.
As someone who has devoted a lot of time to learning things, I became aware of how the availability of huge amounts of data that can be searched efficiently by what we called "googling" changed things pretty profoundly.
We used to spend a lot of time learning and memorizing things, because if you wanted to easily get them again you had to, as the particular book or other source you were using often wouldn't be available. Even if it was on your bookshelf, finding the exact relevant passage would be very difficult. Since googling became available, you can often say, "If I ever need to really know that again, I'll just search for it." Or perhaps you don't really need to learn it when you encounter it, but know you can find it to learn it if/when it becomes relevant.
Another thing people like me used to do was share our wisdom. Tell or write online (in recent years mostly the latter) what you remembered. Googling changed that in a couple ways. First, the humbling experience of simply asking Google what you thought you remembered, and finding that you hadn't gotten some key things right. Which after a while led to me checking that before sharing wisdom. And then often led to not sharing the wisdom but just providing a link to where it was written up. And finally sometimes not even providing the link, because you know the reader knows they can find out just by searching for it themselves. This particularly affected the case where you in the old days would have explained some key background, like the definition of some key term or phrase. No need to write it up yourself, no need to provide a link, since you know astute readers can search for it themselves. (If you're writing for a large audience, you can provide the hyperlinks to make it easier, but for smaller audiences typically not worth it).
So while it might have been a source of satisfaction or pride to share wisdom I had learned, that rarely happens so much any more. But sometimes I'll still do that, partly because my learning on this score is only incomplete, and occasionally explicitly by saying I enjoy telling the story myself -- if I can hope my readers will indulge me.
So what I write is guided by what I know other people can search for, and maybe more precisely what I believe they know they can search for. The more a question can be defined by a simple unique phrase, the more easily it can be found, and readers know that, and I know they know that. If you refer to Noam Chomsky, you know anyone can find him by a simple search. If the person in question is on the other hand John Smith, you'd better provide more information than that, but you still will likely not have to actually say much substantive about John Smith.
