Every encyclopedia is lossy, by definition. Even the most expansive holds a tiny fraction of human knowledge (which is a fraction of what we could know).

On the other hand, it’s not worse than other analogies.

This.

Also every encyclopedia is full of things that are wrong. People seem to be forgetting this basic issue. Any given authoritative, well respected source will contain mistakes, errors of omission, and downright lies. Part of a proper education used to be that when writing things, you need to site your sources, and the sources can't just be an encyclopedia. I use LLMs a lot, but if anything is really important, I'm going to fact check it and look for other sources.
