Bad human hand creation in AI

@Peter_Frommenwiler0327  that's nothing. My father-in-law passsed away last year, and I was doing his photo for the picture at the head of the casket. His head in the orginal photo was tilted, and I wanted to see if AI can quickly fixed it...as soon as I put a prompt in, and hit enter, my wife comes in, and soon after, my father-in-law head is now changed to a blond guy (fyi, my FIL is Chinese), so I quicky hit regenerate, and then it gave me woman's head, by then, I already knew...I was in the doghouse... I eventually did it by hand...

MidJourney renders hands better. It's still rolling the dice but the odds are in your favor.

If you google this, you'll see that this is nothing special for Firefly/Photoshop; they all do this. It's an excellent illustration of the deficiencies of AI in general. It has no "understanding" of what it's doing. It's just a machine.

EDIT Jane beat me with a more comprehensive explanation - but you get the idea.

It's not just Adobe's Generative AI. Here's one paragraph from Britannica that explains the issue pretty well.

https://www.britannica.com/topic/Why-does-AI-art-screw-up-hands-and-fingers-2230501

"Another issue is that AI doesn’t actually know what a hand is. In two-dimensional images, hands can appear in dozens of different positions: waving, flexing, holding an object, clenching a fist, or poking out of a pants pocket, partially hidden from view. Humans know that these visual discrepancies illustrate how a hand works. AI, without access to the three-dimensional world, knows only how a hand appears. Identifying a fist, thumbs-up, or peace sign as a hand is an impressive feat for AI, and we can hardly blame it for assuming a real hand could be a combination of the three."

You can use traditional methods in Photoshop to clean up Generative Fill.
