I don't get it get why some folks just don't seem to like the idea. Sure, I understand disagreement with methodology. Figuring out what charity is most cost effective isn't always straight forward. Mosquito nets save X number of lives, sure that pretty straight forward but education extends and improves quality of life but it not exactly a straight line or even all that easily quantifiable. So, sure, how you decide what's more cost effective is not easy and easy to criticize but some folks seem to think the whole notion is some sort of sham. Shouldn't we try to figure what the most effective way to spend on causes is? Partly fed by Sam Bankman Freed I'm sure.
