Mr Mark Zuckerberg and wife Priscilla pledge $3bn to wipe out ALL disease in 80 years

Founder of Facebook Mark Zuckerberg has a goal that's even more ambitious than connecting the entire world to the internet: He and his wife want to help eradicate all diseases in the world by the end of this century.

Zuckerberg and Priscilla Chan are committing $3 billion over the next 10 years to accelerate basic scientific research, including the creation of research tools — from software to hardware to yet-undiscovered techniques — they hope will ultimately lead to scientific breakthroughs, the way the microscope and DNA sequencing have in generations past.

The goal, which they are unlikely to live to see accomplished, is to 'cure, prevent or manage all disease' in the next 80 or so years.

They acknowledge that this might sound a crazy, but point to how far medicine and science have 

come in the last century — with vaccines, statins for heart disease, chemotherapy, and so on — following millennia with little progress.

'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,' Zuckerberg said in an interview. 

He and Chan have spent the past two years speaking to scientists and other experts to plan the endeavor.

He emphasized 'that this isn't something where we just read a book and decided we're going to do.'

Chan's work as a pediatrician seems to be a big driver in their couple's decision to take up this latest cause.

'I've been with families where we've hit the limit of what's possible through medicine and science,' Chan said. 'I've had to tell families devastating diagnoses of leukemia, or that we just weren't able to resuscitate their child.'

The couple spoke with The Associated Press in their home in Palo Alto, California, where their infant daughter, Max, had just woken from a nap. Their dog, Beast, came by to sit briefly during the 25-minute interview.

Zuckerberg and Chan hope that their effort will inspire other far-reaching efforts and collaboration in science, medicine and engineering, so that basic research is no longer relegated to the margins.

'We spend 50 times more on health care treating people who are sick than we spend on science research (to cure) diseases so that people don't get sick in the first place,' Zuckerberg said. 

Eric Lander, a professor of biology at the Massachusetts Institute of Technology and director of the Broad Institute at MIT and Harvard, said he's had some 20 conversations with Zuckerberg and Chan over the past year about the initiative and called their goal 'the right kind of goal for thinking about that kind of timeframe.'
