It's very cool from a geek / technological point of view but I can't help but think that non-lifesaving technology ultimately brings us little good, if you look at the big picture.
"Lifesaving" is a pretty nebulous concept. Does a plow which enables higher crop yields and thus less starvation constitute as life saving? Or a weather satellite, which allows prediction of rain patterns and more efficient irrigation usage? Modern technology is all interconnected, and only a few extreme leaf nodes could be unambiguously declared non-life saving.
