Parenthood will do crazy things to people. For example, on the same day Mark Zuckerberg and Dr. Priscilla Chan announced the birth of their first child, they also announced they'd be giving away 99% of their Facebook stock—worth nearly $45 billion, CNN reports. Zuckerberg and Chan posted an extremely lengthy open letter to their daughter Max on Facebook Tuesday. "Max, we love you and feel a great responsibility to leave the world a better place for you and all children," the letter reads. "We wish you a life filled with the same love, hope, and joy you give us. We can't wait to see what you bring to this world." It follows similar Facebook posts from the couple about their experience with multiple miscarriages and Zuckerberg's decision to take two months of paternity leave.
Reuters reports the couple will be putting the proceeds from their Facebook stock toward their nearly formed charity, the Chan Zuckerberg Initiative. The charity will work toward "advancing human potential" and "promoting equality," starting with "personalized learning, curing disease, connecting people, and building strong communities," according to the letter. To start, Reuters reports Zuckerberg has committed to putting up to $1 billion of his stock toward the charity every year for the next three years. Wired points out the letter—expounding on Zuckerberg's passions—seems like it was written more for the public than for his daughter, but that's OK. "We’re pumped to watch the young CEO navigate the intricacies of parenthood while sitting atop one of the world’s biggest companies," Wired states.
