I don't actually value lives saved very much. Death's just not that big a deal. I'm more interested in producing states of wonder and joy. I want to bring as many people as can to the level of eduction and self-awareness where they can appreciate the incredibleness of the world. The saddest thing that I can think of is that there are are hundreds of thousands of people who are just as smart as I am who were never given the opportunities or encouragement that I was to come to love the world. I'm in the business of poverty elevation and disease eradication, because removing those constraints allows us to maximize fully flourished human lives. Similarly, I care about a singularity because the amount of insight to which the species has access will go through the roof.

I use "live-saved" since, as you point out, it's a sort of hot-word to which people react and associate with "doing good."
