Oh no, much better, communication with alternate universes, including ones that have just split. Effective population for purposes of developing technology and knowledge goes up an order of magnitude or more, massive economies of scale. Population for purposes of using up resources effectively the same. Drug testing better than double blind because you use the versions of people from two just split universes. Group A gets the placebo in this universe and the drug in the other, group B gets the drug here and the placebo here. No difference in the genetics, disease status etc. of the placebo and control groups.
