Uber's system automatically raises prices based on surges in demand. There's no human intervention involved. So getting all upset at Uber for this is pointless.
So let me get this straight? If I program a machine to do something heinous automatically, I'm not responsible because "there is no human intervention"? Seems like there was a fuck of a lot of human intervention in writing the algorithm. Somehow, I doubt this argument would hold water in a court of law.
Regardless of whether you think this is right or not, at least think about what you're saying before you open your mouth and let the stupid out.
