They are very careful to not mention certain things in their video: nothing involving the computational nature of the human identity / "consciousness". Nothing we would call "whole brain emulation".
I have little doubt that what they choose to mention, and what they choose not to mention, in their video is driven more by signalling considerations than by what they consider to be technologically (in)feasible. Can they do what they claim? Create a model of the human brain detailed enough to obtain non-trivial information about brain diseases and computational processes used in the brain, but coarse enough to not have moral implications? Of course I do not know the answer to this question.
Kurzweil, who is widely agreed to be rather optimistic in his predictions, predicts
They seem t be purposefully dodging talking about moral significance of the simulated brain, which is worrying...
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
