it's not just a war of capabilities but a war of UXes. Is an 'AI Engineer' going to be an extension of an IDE (that autocompletes your routine or LOC like Cursor) or a 'digital employee' that autocompletes and auto-tests your thought (like Devin). Melty seems to be going down the Cursor route.
As an old-fashioned 'emacs and print out' guy, I prefer Devin type planner interfaces .. iff they can perform. Not quite yet.
