You guys forgot about so called Birthday attack. No, I am not talking about USA drones bombing wedding parties or funerals in Afganistan and Yemen. I am talking about this one https://en.wikipedia.org/wiki/Birthday_attack when lots of random numbers are generated, it greatly increases probability that two random numbers are identical. Somebody should do the math to calculate exact percentage on how likely is to get one collision when there are n numbers of unique bitcoin addresses generated and used in blockchain. But I still think that probability of collision in real life is close to zero, even if birthday attack collision probability is increased several orders of magnitude.
