I have received funding from the LTFF and the SFF and am also doing work for an EA-adjacent organization.
My EA journey started in 2007 as I considered switching from a Wall Street career to instead help tackle climate change by making wind energy cheaper – unfortunately, the University of Pennsylvania did not have an EA chapter back then! A few years later, I started having doubts whether helping to build one wind farm at a time was the best use of my time. After reading a few books on philosophy and psychology, I decided that moral circle expansion was neglected but important and donated a few thousand sterling pounds of my modest income to a somewhat evidence-based organisation. Serendipitously, my boss stumbled upon EA in a thread on Stack Exchange around 2014 and sent me a link. After reading up on EA, I then pursued E2G with my modest income, donating ~USD35k to AMF. I have done some limited volunteering for building the EA community here in Stockholm, Sweden. Additionally, I set up and was an admin of the ~1k member EA system change Facebook group (apologies for not having time to make more of it!). Lastly, (and I am leaving out a lot of smaller stuff like giving career guidance, etc.) I have coordinated with other people interested in doing EA community building in UWC high schools and have even run a couple of EA events at these schools.
It sounds like it would be uncontroversially good to have such a system in place. Have you checked if Ambitious Impact might have looked into outbreak detection? If not, it might be useful, although it takes some time, to get at least some very rough estimates of how much such a system might cost and some transparent estimates of how many lives/how much suffering might be averted by such a system? I could imagine it could be quite affordable and very effective, but beyond the numbers, understanding the different elements of a cost effectiveness estimate will also help readers like me understand the various considerations.
