No, this isn't a case of different people having different opinions about different ways to obtain information during different times. More often than not, I find that the SAME people who act like Wikipedia is the most unreliable thing on Earth unironically trust the FIRST Google Search result they see, as well as everything they've ever seen in ChatGPT.
Need I remind you that Google is LITERALLY designed to cater to your biases? And it's gotten WORSE because the first result you see is NOW AI-Generated. Also, Google is not a source! And AI Chatbots cite THEMSELVES as sources!
Wikipedia on the other hand is curated by REAL VOLUNTEER HUMANS who strive to be accurate as possible. I'm aware that Wikipedia is no stranger to agendas or vandalism, but these editors are quick and dedicated to be as accurate as possible. So much so that whenever a building is on fire, they LITERALLY label it as "Status: Burning". Not burned... BURNING! Meanwhile, Google tells you to put glue on your pizza...
And yes, I know that Wikipedia is not a source. Like Google, Wikipedia is a GATEWAY to sources, and not a source in and of itself. But at the very least, Wikipedia DOESN'T try to give you what you will like, because you'll get what is (most likely) the truth instead, backed up by several CREDIBLE sources that are constantly fact-checked by volunteer humans.
So why do people hate Wikipedia so much? And why do these SAME PEOPLE cite Google and ChatGPT as a source?
People that criticize the use of Wikipedia are generally doing so to intentionally be manipulative. They use the vague confusion around how Wikipedia works to make it look unreliable, then imply that it makes whatever you say wrong.
Generally, it is a fascist take, because fascists hate the idea of a community-based anything. If there is no central authority/boss, then they hate it.
AI is seen as the opposite, it is this one magic entity that you refer to and tells you whatever you want to hear and leads you to believe that they are amazing. Which coincidentally is what all fascist politicians do.
Anyone that considers LLMs to be anything else than worthless has opinions that are as worthless anyway, so I'd advise ignoring them.
