Just like any text editor is doomed to become either Emacs or Word, so any image editor is doomed to become Photoshop.
Too true. I gave up trying to fight it years ago and now write all my documents in Emacs and edit my code with Microsoft Word.
Except Vim of course.
Reminds me of Zawinski's Law of Software Envelopment[^1,2]: "Every program attempts to expand until it can read mail. Those programs which cannot so expand are replaced by ones which can."
