I'm not trying to make excuses for Grok, but how exactly isn't the user creating the content? Grok doesn't have create images on its own volition, the user is still required to give it some input, therefore "creating" the content.

X is making it pretty clear that it is "Grok" posting those images and not the user. It is a separate posting that comes from an official account named "Grok". X has full control over what the official "Grok" account posts.

There is no functionality for the users to review and approve "Grok" responses to their tweets.

Until now, webserver had just been like a post service. Grok is more like a CNC late.

Does an autonomous car drive the car from point A to point B or does the person who puts in the destination address drive the car?
