The hardware for a whole-brain human simulation is not the limiting factor - if we had the hardware right now, we wouldn't know how to program that simulation.

The hardware for a whole-brain human simulation is not the limiting factor - if we had the hardware right now, we wouldn't know how to program that simulation. Of course, the Agile Manifesto says you can develop systems without having a requirements specification or detailed design beforehand, but it also says that questions about when it will be done are off-topic.
