Adobe just added ai and generative fill with inpainting and outpainting
i did a quick test, started with a shot of Troi
then i tried the "extend the background" feature

sometimes it gave me strange results:
i did one test where i selected Troi, and then inverted the selection and
with the prompt "futuristic sci fi panel" this was the result:
this is a good start integrating ai from Adobe i think.
Go to your Adobe creative cloud app and update the new version,
then you have access to the new Photoshop with ai beta.
edit:another test: it took literally 10 sec from this:
to this new background:
