How much of what you do with Photoshop could be done with open source tools instead (GIMP, ImageMagick, etc), versus how much do you really need Photoshop for?

One technique I’ve used for cleaning up AI-generated images, was a Python script driving ImageMagick-and an LLM helped write the Python script (although it took a few iterations, because the LLM’s first attempt didn’t actually work)
