> use cases that have actually improved your life in some measurable way?

"actually" and "measurable" are, to pardon the Claudism, load bearing. If something made my life better in some imperceptible way that makes me happy, why the need to force metric on it? Not having to call Comcast to fake threaten to cancel service made me THREE happier and SEVEN less angsty. That pretty picture made me FOUR smilier. It makes me wonder if we can't just have nice things.
