The professor who helped Google's founders get the company off the ground has warned that President Obama is leading the United States on a "crash course" towards economic disaster.
David Cheriton, who taught Sergey Brin and Larry Page at Stanford University in California and became a billionaire as Google grew, said that America's innovators and investors were being driven overseas in search of opportunity.
The BBC's Matt Frei spoke with Prof Cheriton on the Stanford campus.
