Uber is essentially a Bring-Your-Own-Hardware for taxis. It's sort of "decentralizing" the taxi service, if you will. And laws seem to be antiquated for such a model. I wonder how decentralization of the tech industry, next, would play out if the laws are not written with that in mind. How do you tax a platform that offers, say, AWS but with commodity hardware? How do you ascertain data privacy laws in such a case?
