If i.e. Google would be smart, they would realize that they are digging a hole under their feet, if they seriously consider putting professional content creators on the side-line. The "AI-output" would quickly become repetitive, and out-dated, possibly even ending up digesting just what some propaganda network puts out.
"AI as librarian" would certainly make more sense. I'd even go for "personal assistant". In example, I would ask PAI to compile a table containing links to all published works by Avram Pitch, containing "AI". Right now, I would have to do a search manually, including specific commands to not have the results be flooded with stuff I am not looking for specifically right now. And having PAI, which uses some personal data from me to actually improve my experience - personal data, such as what my preference for file format of the table is, which I can tell-it/customize - that would seem way cooler. And it would arguably be the actual next logical step in the development of the "web-search experience".
And such experience may perhaps not have as much broad appeal, as a "mysterious oracle" does have, or not sound as much of a financial venue as creating a corporate environment, which users are tied to, where they have their daily schedule determined by an algorithm, and where they are eventually told to crush another billionaire's fiefdom. But it would feel more like Web 3.0, opening the door to more quality.
In example, with the mentioned table, and some additions to it, it would save some time towards writing an article in an non-English language, which uses linked quotes, and which may help to create interest in web-stuff in overall. And such could create more traffic for various sites and services, who are then more likely to be able to afford full-time positions, which in turn could mean e.g. more news articles.
Meanwhile, PAIs could help readers to filter what every reader is individually interested in, instead of the quest for an ultimate algorithm, which caters to everyone, while it doesn't necessarily go even beyond being driven by the web-usage of a relatively small group of power-users, who are not really doing anything but to sit in their basement day and night, while flooding the net with their output. Which is good for them, but there are also poorer citizen, who may not even have a smartphone to type on. So an algorithm assuming that the power-users are what the majority says and likes, that makes the online experience in some cases a quite estranged one.
