Tesla's value is surging 'because the vision is so intoxicating'

Scott Galloway, a marketing professor at NYU and author of the new book "The Four: The Hidden DNA of Amazon, Apple, Facebook, and Google," talks about Tesla. He marvels at the market cap discrepancy between Ford and Tesla, saying that the latter company has painted an unbelievable vision, and that people are investing in the future, not anything tangible at the moment. Galloway calls it incredible storytelling, and marvels at how the company has been able to overpromise and under-deliver, all because the vision is so intoxicating.
