Not so much technology, but I'd fund the Howard Society for real. For those unfamiliar, it's a program to identify people who are genetically predisposed to natural long life and pay them to have kids with each other; it's a core plot point in a bunch of Heinlein novels.
I find a lot of people don't understand what eugenics even is. Hell, as Richard Dawkins proved, if you worded it properly you could even get people to rally behind it, which is a huge problem because eugenics is fascist pseudoscience.
