I’d think this is human driven. They give it two images and tell it to morph.
The Left (and frankly some of us too) sees the Bushes as a wanna-be dynasty. What better way to depict that in graphic form than to put a crown on someone?
The computer would see Bush and morph him, but it wouldn’t morph him based on the dynasty perception. It wouldn’t grasp that dynamic.
Then you see Bush’s wife and Jindal. One is trashed as an insult and the other for his more Conservative beliefs.
This isn’t an accidental occurrence IMO.
