A simulated heart does not pump real blood. Also in the process, why should one start or stop at cell level, seems arbitrary, go further down to atoms and electrons etc. or go higher level to mental state or what not. There are completed projects of smaller organism whose all neurons have been simulated, there hasn't been any revelations. Our brain doesn't contain any 'data', so whoever decides to extract data from it will have to decide what the data will be or why it would be of any use. There has also been many objections made on why brain correlates are more or less useless on question of mind/intelligence.

> A simulated heart does not pump real blood. Well, now, a simulated heartbeat implemented in a pacemaker and connected to a pump does cause real blood to be pumped. A real brain adds real numbers, and so does a computer brain. A real brain composes real words, creates real emails, issues payments, requests shipments. Those are not less real than the words, emails, procedures, payments, and shipment requests that computers make today.

  I should have said, A simulated heart in computer does not pump real blood. The thinking involved for a person in issuing shipment is not same as what computer does. These are not simulations. Just similar looking interface. Like a animated cartoon human, compared to a human.

> Our brain doesn't contain any 'data' It absolutely does! Where do you think our memories are stored? It doesn't store it in 1s and 0s like computers, but I think it's fairly non-controversial to say that all of everything you know is encoded in the physical state of the cells and atoms of your body.

  If this assumption is correct then I could see us creating an accurate model of the human brain in the future. But it is an assumption.
