Firefly AI Compositing

I had this idea for photshop but it would may be helpful in firefly as well. Something that could leverage the power of AI that would be game changing and useful ,would be the ability to take A photo and automatically composite all the elements into layers, even to go as far as filling in the areas you dont see.

So for example imagine a picture of a woman walking in front of a city with cars and buildings. AI could seperate the woman into the top layer, and the city/cars/ect into another layer and fill in the area where the woman was so if you move the woman layer there are no building gaps anymore. Maybe you could select how many composite layers you want to generate or maybe hand select a single element you wish seperate and composite for you to fill in the layers below.

This is also useful for editing elements easier and work more freely.
AI Video already sort of does this, and you could do this manually which is time consuming but instead we are just taking the same technology and using AIs'  compositing abilities in a useful way directly inside a photo editior like photoshop.
