I think it’s good that it exist though it being own by giant corporation and the copyright issues along with it is questionable. But in terms increasing productivity it’s obvious. Though everyone can generate but not everyone has an artistic mindset and be able to produce what their thinking. Artist should leverage it to increase or get inspiration for their next big thing, essentially treat it like those custom brushes but on a higher level. Imagine animators having the ability to tweak movements in between frames making it super crisp without much effort. All they will have to do now is produce key frames and describe the in between process. Graphic artist generating starting scenes which they can work further to do some concept art. No longer having to spend overtime animating a scene for an episode that is to be aired the next day. A mangaka having to draw backgrounds for their manga. This means no need to do overtime to reach a certain quality that customers demand. Though the question it replacing artist entirely at some point in the future, I don’t think it will happen since people in general especially to art wants a human touch on things. Though if that time comes we might have a bigger question to answer.
