"In some individual actions a very high level of simulation was achieved, e.g. in chess or Go. However, we are still very far from being able to model all human behaviors, even very primitive ones. The number of decisions made every day turns out to be so huge that it will take a long time until a device capable of dealing with all the problems, a device of which actions would be indistinguishable from human ones, will be created. We cannot predict if and when this will happen, because from previous experience it appears that no forecast in this area managed to meet the reality."
