> That layer has largely dissolved. Search engines replaced the card catalog, algorithms replaced the reference interview, and AI summaries are now stepping in where a librarian’s judgment about source quality used to sit. What’s been left in place of all that professional mediation is a search bar and the assumption that you’ll figure it out. - https://cardcatalogforlife.substack.com/i/188856309/the-skil...

An unfortunate conclusion that smuggles in unwarranted good-old-days nostalgia to an otherwise excellent overview. The previous system that they're describing had serious problems, limited access to raw data compared to now, and could not have scaled up to the level of access to information that the internet provides.

The information environment prior to the early 2000s was quite terrible. We shouldn't pretend this was a golden age of truth-oriented gatekeeping, although there were certainly gatekeepers. There were a lot of misconceptions, errors, and unchecked biases on dead trees and in late 90s databases. The idea that those librarians, researchers, editors, fact-checkers were aligned with anything you might care about is also unsupported and dubious.
