I asked Claude to translate a book title from Hebrew (well not translate exactly but locate the original English title of the same book).

That's not a language I speak or generally have anything else to do with.

I then asked it an unrelated question about a science topic and it returned something with a citation. When I clicked on the citation, not only was it not relevant to the science question it claimed it was cited to support, it was basically a conspiracy theory from the 1970s about Jews controlling the media.

Which somehow seems even worse than my usual experience of the link being totally made up dead end.
