Cortana was doomed the moment Microsoft gave up on Windows Phone. It could never become as integrated with the mobile os as the competing assistants. Even if Cortana was better, it wasn't always listening. And on a desktop the assistants are still not sufficiently versatile at home, and not compatible with the open office environments at work. Also Cortana was always good at languages it suported, but it couldn't provide good localized content for most of the world.
