Couldn't disagree more. Notepad is a place to dump snippets of unformatted text, for a temporary duration unless I explicity save the file. I already didn't like that they added the tabs feature and autosave recently.
If I want to do writing I'll use one of the 6 tools on my PC more suited to that task.
As a counterpoint, I'm on macOS where their latest AI writing tools are now implemented system wide. I also use TextEdit (approximately equivalent to Windows Notepad) and the Stickies app for similar text dumping ground behavior and yet, having the AI writing tools available on those two apps is incredibly useful. I often don't use it at all, but there are things I want to run through it and not having to move the text yet again to another app is nice.
It's _also_ useful in my apps dedicated to writing and even the text areas of browsers. I think it's all about implementation though, Apple's writing tools are quietly buried in the context menu for most text inputs. Microsoft has a tendency to be pushy and in your face about their latest AI offerings like shoving it into the Start Menu, or making it a prominent and visible element of their UI (Copilot in VSCode, even when you're not a subscriber) and the Verge's screenshot isn't enough for me to judge this by.
Word is the perfect place for it? Or OneNote. This would be like if Apple added AI rewrite to TextEdit instead of Apple Notes. Notepad's only job is to open text files as fast as possible.
> And clearly its a useful too in a writing app that users would like
I don't believe it's useful. I don't think Notepad is a "writing app." And I'm fairly certain not a single user in the history of ever has asked for this.
I get your complaint in general, but it does not seem like this is a good example of throwing random unrelated stuff in.
