I think its amazing what computers are creating. It's also liberating for people who love art but who can't create it themselves for whatever reason - they can ask for a painting of any scene in the style of any artist and get a cool rendition to enjoy!
I agree that hand-painted art is always preferable, but many people simply can't afford it. This way they can still explore their creativity and foster that appreciation of art. Maybe that's a stepping stone to putting aside money to spend on artists.
