I haven't seen anything yet on how much recent Wikipedia content is generated by systems like ChatGPT... it appears to be an issue however:
> "Wikipedians like Knipel imagine that ChatGPT could be used on Wikipedia as a tool without removing the role of humanity. For them, the initial text that’s generated from the chatbot is useful as a starting place or a skeletal outline. Then, the human verifies that this information is supported by reliable sources and fleshes it out with improvements. This way, Wikipedia itself does not become machine-written. Humans remain the project’s special sauce."
