There is usually no quality-control on AI-output, because people are lacking time and/or competence doing it, which are also the reasons why they are using AI.

And AI still can make up things, which might be fine in some random internet-comment, or some irrelevant article about something irrelevant happening somewhere in the world, but not with a knowledge-vault like Wikipedia.

And, we are talking here about Wikipedia. They are not just checking for AI, they are checking everything from everyone and have many many rules to ensure a certain level of quality. They can't check everything at once and fetch all problems immediately, but they are working step by step and over time.

You should be embarrassed for making such a statement.
