A billionaire is giving away a significant fraction of his money to coronavirus relief. Jack Dorsey has said he’s donating $1 billion to the cause. This is a good start — he says it’s over 25% of his net worth — with a couple of reservations: he has only said he’s going to do this, and rich people have a reputation for not following through; distributing that much money is a huge, difficult task and Dorsey is not an expert on funding biomedical institutions; and damn, he shouldn’t have that much money in the first place.
He also still has a couple of billion dollars more in his pocket. He’s not going to be hurting.
