Looking at Amazon's Q1 2016 Financial Results [1], page 8, we see that net sales of non-AWS amounts to ~$26B, and AWS is ~$2.5B. From the Segment Highlights section (same page), AWS sales is 9% of total sales. AWS beats non-AWS income only because there were losses in international; ignoring international, it's a $16m difference. Looking at page 14, Media sales in North America and International sum to $5.6B. Media sales alone is double AWS's sales of $2.5B (page 13). Profit margins are way higher for AWS, so there's still a lot of room for a larger income difference between the two segments.

Retail Profits = (702 (Domestic) + (- 135) (International)) < 718 (AWS)
Amazon made more money on AWS than their retail side.
My concern is that Uber is already considered "expensive" by customers, and that's at a massively subsidized rate - how will customers react when Uber wins the price war, destroys the competition, and then has to actually raise prices? and not just raise prices to break even, and not just to make a profit, and not just to grow the currently non-existent fleet of physical vehicles (self-driving or not), but to also make back the US$billions lost to win the war of attrition?
Facebook as one example also lost a lot of money (not $1.2b in six months mind you) for years before finally turning profitable. What was there for them to lose money on, social networks are just a couple servers, right? No, they were building out a massive foundation for the future. And now they're a money printing machine.
Because later when the subsidies are dropped and the product price rises, the demand will increase?
>All of the reasons why cabs exist can be served by Uber better and cheaper.
I don't necessarily agree here, because Uber always has to have drivers standing by. If usage in the area isn't high, average people won't become reliable drivers because their app will usually be empty and they'll give up. Thus, Uber would probably be more efficient if they paid the same small subset of people to be available at set intervals, and at that point, what's the difference between Uber and a typical cab company?
In markets that aren't hot enough to get normal people in the driver pool, Uber may do better just to open their platform to local cab companies.
That's the idea at least.
The reality of the economics is likely different but that's how it works in theory. Now they are likely paying drivers to be out looking for rides to ensure that service isn't disrupted, and yes they need to subsidize that as others are mentioning.
