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.
