Eh. It really depends on the topic. I am a Wikipedia addict and I would never tell anyone that Wikipedia should be used for anything beyond surface level familiarity. Ideally you start with Wikipedia then move on to better quality sources. The problem with Wikipedia isn’t necessarily inaccuracy, but lack of information and bias. I’m not talking about right wing conspiracies saying Wikipedia is too liberal, but rather I am talking about things in history where a specific view is presented and alternate views are not. This is especially common in situations where modern scholars are questioning historically mainstream views. I suspect this is because the editors simply aren’t aware of these developments and are accessing more available older sources, but it can bring in bias. This can also happen in science and engineering as well. Plus there is the classic Wikipedia problem where some random B list Marvel superhero or star wars extended universe side character has an extremely high quality Wikipedia page and a relatively important historical to figure has a very basic overview. Wikipedia is incredible and one of the greatest achievements of Humanity, but it’s got some flaws and I don’t think that it’s wrong to tell students not to rely on Wikipedia. It’s kind of like all the same issues with ChatGPT but way less severe and way more subtle.
