Thanks so much for your support!
I heard about Manifund from Sophia actually! @spunge and I met at a rationality camp in New Hampshire last week and exchanged a ton of amazing ideas and resources.
On the topic of relevance to EA, I feel like human augmentation is an overlooked part of longtermism compared to popular fields like biosecurity and AI alignment. I believe it's just as important to improve the comfort and longevity of future humans as it is to consider the longevity of humanity as a species. I'd love to hear your thoughts on this!
