Another Idea that Adobe can do thats unique is making an AI brush. Theres already realtime AI that fixes peoples drawings if they cant draw , well what if you use the same realtime technology but in a brush that can benefit those who do have artistic skills or anyone really. So Instead of just making an entire image for you, this tool can help in tedious task for special EFX giving artist quicker workflows.
Let me explain:
Say you are trying to paint fire and as you paint (or after you release your stroke) it makes the fire look real/more finished. For making special EFX this could be super helpful even as a base. It Can be used for paintingGrass, leaves, fire, snow, dust, wind, branches, wood carvings, windows, hair, sparks, glows, energy beams, ect. instead of just using a normal brush that just gives you stamp info only. Can see this being something unique and helpful. You could even make it an AI layer that enables you to edit the context already made or rasterize it like you do a smart object.
