One of the things that lets me work late into the wee hours filled with an unbearable amount of smug self-satisfaction is I have the extraordinarily rare privilege of working in one of the very, very few areas of tech that is largely environmentally benign, incontrovertibly pro-human, almost impossible to weaponize or use for evil- and all I have to do, my sole daily task as a person on conscience, is keep it out of the hands of profiteers who would try to make it scarce and unaffordable.
Very, very few people are blessed with an opportunity to do incontestable, pure good like that on such a large scale.
