I think it definitely was a huge breakdown in academic's to adapt to new technology, and it is at the core of a lot of the societal problems we face today. Of course, a lot of the reasons for this were by design at the hands of a few corporate actors, and they share a lot of culpability.

There are philosophical underpinnings too - a lot of academics are still caught up on modernism (which would rightfully distrust new internet sources in favor of legacy sources of proven idealistic knowledge) vs. Postmodernism, which would provide a framework to recognize the truth in these systems.

One thing to keep in mind is that computers and the internet are still extremely new, and we are still figuring them out. It has only been a decade and a half where everyone has a general purpose, internet connected computer in their pocket.

There's still good and plenty fuckery that can happen with citing books, though. Depending on the obscurity of the book, whether or not it's out of print, or just has been outright destroyed, it might be really hard to access a copy, and check the source, especially if someone doesn't have access to the internet archive or library genesis, i.e. digital scans of said book. There are reprints and new editions, sometimes not noted by the author of the citation (the author might have no way of knowing, depends), which can change or remove quoted passages. The internet also contains the ability to mass copy anything you want, and cite that copy, like what the internet archive does with the wayback machine, so if you have a citation of a webpage it's probably a good idea to copy that in time and then spread it around anyways just for the sake of posterity and accessibility, especially if it's obscure or is likely to be changed or removed. Same as you might for a book, except much easier, it's much harder to copy a whole book in context and spread that around compared to a webpage.
