An anonymous reader writes: The Facebook stock currently held by Mark Zuckerberg and his wife Priscilla Chan is worth roughly $45 billion. Today, the couple posted a letter addressed to their newborn daughter outlining plans to give away 99% of that stock so their daughter can "live in a better world." They say, "Our initial areas of focus will be personalized learning, curing disease, connecting people and building strong communities." The letter also includes a long list of problems that need to be solved and situations that need to be improved: human health, learning, clean energy, equality, unhealthy childhoods, and more. They go out of their way to mention that many of these will not be solved quickly, and will need investments on a 100-year scale to be worthwhile. They're making internet access another major issue: "The internet is so important that for every 10 people who gain internet access, about one person is lifted out of poverty and about one new job is created."
