There is quantum probability, which is advertised to come from quantum chip random number generators https://www.idquantique.com/random-number-generation/products/quantis-random-number-generator/ (to be concrete about it), where the claim is that the series of 0s and 1s one gets from then is true randomness (coming from a quantum source). Now in Sean Carroll's MW presentation, the computer with one of those boards in it would duplicate and there would be a 0 branch and a 1 branch with each 0 or 1 generated. So at the end of seeing 01001110 on your screen, there would be 2^8 computers (and yous) in that many worlds. "Stochastic" (Greek word origin) is just another (cooler, some think) for "random". In a probability theory track at university: random processes, stochastic processes, same damn things. Assuming there is just one world, there is just one computer at the end of seeing 01001110 and no other computers in other worlds. @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
