Features like the magic cursor look cool: an infinitely flexible context menu. However, context menus make it clear what you can and cannot do. If the magic cursor can't "do everything reasonable", it'll be just as usable as Siri.
I'd be more likely to believe them if they had already implemented this feature on their Pixel phones, but they haven't so I expect it probably isn't "done".
