Yeh, but how likely is it to payoff as much as they're hoping for organically? My guess is that's pretty close to zero, probability-wise. Which should tend to discourage such investment. The only reason it isn't discouraged is because the behavior of crazy investment becomes its own semi-unintentional pump and dump scheme. The initial investors can strike it rich, even if Uber's not really worth $17 billion in the long run... just so long as the second-wave investors think that it's really worth $20-something billion. Investment really isn't even investment anymore, so much as it is gambling
