Elon has signed Buffett's giving pledge. So (if he's true to his word) eventually he will donate the vast majority of his wealth to charity. In the meanwhile, most of his net worth is tied up in shares of his companies. Selling or directly donating shares means giving up more control, and if he believes his companies will outperform other investments (or even just that it beats inflation), there is a non-clear moral tradeoff even for a strict altruist- do I donate now to solve problems now, or do I hold onto my money so it can grow and solve more problems when I donate later?
