Uber isn't built on a tower of fraud like Theranos, it's a behemoth that changed how transportation works. Travis is going to be a billionaire many times over when the stock is liquid.
He started a taxi service with a slick app to order rides. He was successful by willful criminality, disregarding inconvenient regulations and laws. His company can't retain employees and is burning cash. Their only viable path to profitability assumes no regulatory fallout or serious competition.
He did not change how transportation works. He got where he is through a combination of luck, good timing, and criminality masked as 'disruption'.
Travis is a piece of shit, but you seem confused about how much value Uber has provided the world. Even his most ardent critics are willing to admit that.
Have you ever spoken to an African American what it's like to hail a cab? Read the estimates on the number of drunk drivers taken off the road?
