That's not the point. Copyright law - at least the European versions of it - requires a human creator. So the output of an algorithm is not protected under copyright law in general, even if the output appears to be "creative". If the output includes parts of a pre-existing work by a human creator, then it might be subject to copyright law, but in favour of the creator of the pre-existing work.

Of course the output of an algorithm is covered, if there is creative input. Otherwise nothing generated from photoshop would be protected. And creativity is the point. As a previous post mentioned, "creative powers of the mind"

When you edit images in Photoshop you are the actor and it is your (hopefully) creative result.

You're ignoring a huge grey area.

Many works of art involve processes and the line between "process" and "generated" is very fuzzy.
