I've heard the effect of internet compared to the effect of the printing press.
For the people on the other side of the curve from the village idiot that was true. Before the internet we (on HN I think most of us are on that side of the curve justifying the use of "we" here) had libraries and we had elaborate systems for indexing and searching [1] and providing notification of new information in our areas of interest.
We could do then most of what we now do on the internet as far as getting and processing information is concerned, just slower and we usually had to be fully clothed while doing it.
Like the printing press, what the internet did for us was make it so we could get that information faster, cheaper, and we could do it from home in whatever state of undress suited us.
For people on the village idiot side of the curve, the invention of the internet was not like invention of the printing press.
It was like the discovery of fire.
[1] A good example is a law library. Besides the books that contained the chronological record of cases and decisions from a given court, we had books that organized those cases by topic, books that provided summaries of the key legal points of each case, organized by topic, books that provided cross references for each case showing what later cases cited it, which points of the case they cited it for, and whether those citations were agreeing with it or overruling it.
