But really...

None of these scenarios will likely cause Uber serious harm in the long run. Uber is excellent at what it does, and investors are going crazy for Uber.

Some of Uber's earliest markets are basically minting money, generating hundreds of millions of dollars in revenue annually. In November, Business Insider obtained an internal Uber presentation that was created in early 2014. Most of the data is just from December 2013, but even so, the data within the document gives every indication that Uber is far from being done growing.

In its biggest markets — Washington, D.C., New York City, Chicago, San Francisco, and Los Angeles — Uber logged more than 100,000 trips per week as of last December. Here's Business Insider's Alyson Shontell:

In December 2013, Uber generated about $11.7 million in Washington, D.C. (a ~$141 million annual run rate). It generated $26 million in New York City, or an annual run rate of $312 million. In Chicago, Uber generated $12.7 million for a run rate of $152.4 million. In San Francisco, Uber generated $17.7 million, a run rate of $212.4 million. Los Angeles generated somewhere between the revenue of New York and San Francisco.

These run rates would generate about $1 billion a year, and that doesn't even take into account Uber's growth in 2014. Year over year from New Year's Eve 2012 to New Year's Eve 2013, Uber's growth rate was a whopping 369%.

Sources close to the company have said Uber's gross revenue is expected to hit about $10 billion by 2015. Since Uber keeps 20% of gross revenue, the company would be keeping about $2 billion in net revenue.

Business Insider's Henry Blodget adds that Uber's revenue growth rate was 300% this year, and next year it's expected to be another 300%. Blodget also says investors expect the company to have an initial public offering in the next few years, at a valuation of $50 billion to $100 billion.

For comparison's sake, Facebook achieved Uber's $41 billion valuation in its seventh year — two years before Facebook went public in 2012.

The reason this is happening is Uber provides something of value: It gets you anywhere you need to go at a reasonable price. It sounds like a simple concept, but Uber was the first to perfect this process. You just tap a couple of buttons on your phone and you can see your car and driver on a map, heading your way. The driver won’t pick up anyone else, so you don’t need to fight people off the street to get a ride. And unlike cabs, Uber drivers must be on their best behavior, since negative reviews can affect their ability to drive for Uber in the future. Moreover, your credit-card information is always saved in the app, so you don’t need to fumble for your wallet at the end of the ride. It’s not perfect, but it’s exceedingly better than taking a random yellow cab off the street.
