Hi Ariel! These are interesting points.
For investments, private investment opportunities are not better than public ones on a after-fees basis (in fact, they’re much worse). Private investments do a lot of shady things to make their returns look better than they actually are—and in the US they can get away with it because they’re much less regulated. A great source of information about the problems with private markets is this podcast.
Having more money shouldn’t necessarily change your risk profile either. While you might be more able to task risk, you also have less need to take risk (people with smaller amounts of money may need to take risk to have a decent chance of meeting future consumption needs during retirement). Additionally, even if a windfall did change how much risk you wanted to take, it wouldn’t change the tools you should use to achieve that level of risk.
I definitely agree that a windfall should change your approach to political giving. However, I’m not sure why switching from being a small donor to an EA org to being a major donor would lead you to change how you give (assuming that the org has room for funding). For any grant makers, even small ones, their room for funding is essentially unlimited because they can always start directing the money to new causes if their existing causes don’t have room.
This is really cool! If I might make one observation, the default assumptions (counting animal lives + assuming that AI is going to destroy the world) are not going to be understandable to most people. I think most people would assume that a list like this would count human lives that have already been saved, not ones that might be saved in the future. If the goal is to appeal to a broad audience, it might make sense to make more standard assumptions by default.
If you want to highlight animal advocacy and existential risk as cause areas, it might be helpful for the main page to show lives saved broken down by human/animal and certain/uncertain or current/expected future.
Also, I think there are huge issues with the way the population cause area is framed:
It seems to suggest that causing an additional person to be born counts as “saving a life.”
It says “This effect captures welfare gains from charities that increase the number of wanted births in rich countries through noncoercive means” which seems to suggest that people being born in rich countries is good while people being born in poor countries is neutral or bad.
