Vinod Khosla

By his own admission Vinod Khosla knows very little about the healthcare system and very little about medicine.

That hasn't prevented the former co-founder, chairman and CEO of Sun Microsystems and now a venture capitalist to play a distinct role in shaping the future of healthcare. Or saying provocative things like in the future technology will replace 80% of what doctors do today. 

Or that "Misdiagnosis is as big a killer as breast caner," as he told an audience last year.

Khosla firmly believes that entrepreneurs outside the healthcare system will be responsible for radical, disruptive change and has put his money behind companies that fit the description. 

For instance, through his venture capital firm Khosla Ventures, he has taken bets on new and exciting startups like AliveCor, that has created a device that snaps on to the back of an iPhone giving it the capability to take ECGs; and wearable technology startups like Jawbone, Misfit Wearables and recently Quanttus. 

Here's Khosla talking about the problem of human doctors at the closing keynote of Stanford's Medicine X conference in September.
