Facebook's chief executive Mark Zuckerberg and wife, Priscilla Chan have vowed to spend $3bn over the next decade to try and cure all diseases. The Chan Zuckerberg Initiative, the limited liability company into which Mr. Zuckerberg and Dr. Chan put their Facebook shares, on Wednesday said it would invest at least $3 billion over the next decade toward preventing, curing or managing all diseases by the end of the century. "So if you even just assume that we'll be able to continue to make progress on that same trajectory, then that implies that by the end of this century we will have been able to solve most of these types of things," Mr Zuckerberg said in an interview.

In a speech to introduce the health initiative at an event in San Francisco on Wednesday, Dr. Chan said the work to cure disease was in keeping with her organization’s mission to advance human potential and promote equality. She gave an emotional preamble, describing how a high-quality education helped her succeed as the daughter of Chinese and Vietnamese immigrants. “We want to dramatically improve every life in Max’s generation and make sure we don’t miss a single soul,” Dr. Chan said, referring to her and Mr. Zuckerberg’s infant daughter, Maxima. “We’ll be investing in basic science research with the goal of curing disease.”
