CEARCH did a shallow dive into this (https://​​docs.google.com/​​spreadsheets/​​d/​​116DqgnzADo8zAmJ_QAp9AKcjKPMlgBs2Hc9E7SSAASM/​​edit#gid=0) and our preliminary conclusion is that the marginal expected value of funding life extension research doesn’t meet our threshold of 10x GiveWell. A lot of uncertainty, obviously, but generally things look good upfront and worse later, so this wasn’t a promising sign, and we decided not to spend more time on this.
