You do not and can not know how what I was calling a Theity cares. It is itself a very primitive idea that the caring must manifest as heavyweight, visibly-obvious intervention into everyday life. I do not deny that this is certainly how many or most conceive of it but it should be pointed out that not all religions that contain Theities have this idea actually deeply embedded into them (as opposed to deeply embedded into the minds of the bulk of practitioners), but actually can still work with a relatively subtle Theity using the power of incomprehensibly vast intelligence to accomplish their goals through the smallest of possible changes, an elegant approach.
(Actually Kurzweil's characterization of religion is rather paper-thin, too: "Presumably, millions of those killed were theists, believing that their “theity” would “look out” for their welfare." I know that's not intended as an explanation of The Totality of Religion in one sentence, but I still shouldn't even have to describe how this does not match up with the contents of many religions, particularly including Christianity which promises persecution, explicitly, several times. I think many religions and many actual expressions of religious are rather more subtle than he is willing to give credit for.)
