If you feel dirty, sorry. I do, however genuinely believe you and a lot of other people do not fully understand Elon and his motivations and thought process (if at all).
There are many, many organizations that could benefit from his billions. You brought up his (undiagnosed) autism. How much has he given to autism charities?
Have you ever had a thought that allocating his money may have less of a long term positive impact if he just donated it to various charities instead of allocating it towards more long term goals? Not saying it would or wouldn't, but did you even consider that?
I can't think of any examples on top of my head, but after watching tens of hours of his interviews and such, I can asure you he himself believes his money would do more net good how he is allocating it now than if he just donated it all.
