Tim Cook has big plans for his vast wealth: It’s all going to philanthropy, he revealed in a Fortune interview. The Apple CEO — who’s currently worth around $112 million, and holds restricted stock that could be worth up to $665 million — said he’s already been making donations quietly, but he’s also looking forward to taking a deeper approach to the whole endeavor. That could involve starting something similar to the Bill and Melinda Gates Foundation, the Microsoft co-founder’s non-profit which manages his philanthropic efforts. Cook also plans to cover his nephew’s college education, like the rich uncle that he is. Cook’s open approach to philanthropy differs from his predecessor Steve Jobs, who was widely criticized for not donating enough. His wife, Laurene Powell Jobs, revealed after his death that the family actually donated tens of millions anonymously for over two decades.
