Would you be happy if ML detects that you are trying to capture the moon and replaced your shot with a memorized picture of the moon with match ing size and orientation ?

Autoencoders can presumably do this except that it would be operating at levels of patches rather than the entire Moon.

No would be unhappy :(

ML models on some Samsung phones did exactly that.

It was probably a result of an explicit company charter but such things can happen with modern ML models quite unintentionally.
