Facebook CEO Mark Zuckerberg and his wife Priscilla Chan welcomed their daughter, August, into the world on Monday evening.
In an emotional post on Facebook, Zuckerberg writes, “When your sister was born, we wrote a letter about the world we hoped she, and now you, will grow up in – a world with better education, fewer diseases, stronger communities, and greater equality.”
Mark writes about about how he hopes advances in science and technology will allow Max and August’s generations to live “dramatically better lives.”
“The world can be a serious place. That’s why it’s important to make time to go outside and play.”
