I don’t think predating longtermism rules out Wave. I would count Open Phil’s grants to the Johns Hopkins Center for Health Security, which was established before EA (let alone longtermism), because Open Phil chose to donate to them for longtermist reasons. Similarly, if you wanted to argue that advancing Wave was one of our current best options for improving the long term future, that would be an argument for grouping Wave in with longtermist work.
(I’m really happy that you and Wave are doing what you’re doing, but not because of direct impact on the long-term future.)
