I've had a quick play with one of the AI programs and it generated some interesting pictures based on the words I typed in, but I don't really think I could 'claim' them as my own work. To my mind it's not all that different to raiding Google images for picture elements and combining them into something 'new', it's ultimately just stealing someone else's work. As a photographer I'd be a bit put out if I discovered someone was using parts of my photos to create their own pictures, I'd be more that just 'put out' if I was a professional photographer and earned my living taking and selling photos.
