It’s practically impossible to take pictures of a famous monument without having other people in the frame (usually they’re posing for photos themselves). AI can remove them, with varying degrees of success.

Ironically, it would probably be easier for the AI to generate the photo of the monument without the people. I mean, for famous monuments, whatever photo you're about to take, you could find 10 better ones already on-line, taken from the same point and perspective, and uploaded to Flickr or Instagram or wherenot.
