I don’t think Uber ever can make money…unless it invents self-driving car. It’s just math.
However, I think it is unfair to compare Amazon cash burn with today’s tech cash burn. In Amazon days, Internet just started to grow, so there isn’t many Internet users…it takes years for Amazon to get 1 million users (which was a big deal back in 1997). Today, tech grows at much faster pace, given most business has higher upfront costs to acquire a customer, their corresponding higher cash burn could be a positive rather than negative sign.
