Theoretically a human brain integrated into a robot body could have the longest lifespan and be the most efficient in the work force. Disease would be minimal. But is it in the realms of possibility?

You don't have to answer all the questions.

  1. Could you still have a nervous system through electric impulses imitating the sense of touch?

  2. How would you nourish your brain to sustain life if you don't have a stomach?

  3. Procreation would have to be done prior to becoming a human robot, as this would simply not be possible.

  4. What would the new estimated lifespan be?

  5. A bionic heart would be the most optimal, but would this be possible?

If disease became rampant and technology is very advanced you never know what is in the realms of possibility.

  • $\begingroup$ Where exactly is a robot superior? There is no robot which can stay operative for 80+years like a human body can do. $\endgroup$ – L.Dutch Aug 30 '17 at 5:05

This scheme wouldn't work for multiple reasons, but I will cite just one:

Brain cannot work as an isolated organ, even assuming you can give enough nutrients to keep it healthy and functioning (this could be done, in a reasonable future) and are able to plug into it input/outputs to the robotic body (this also, with a certain difficulty, mainly due to needed number of nanotransducers, is thinkable) what it will stop you is the brain works in a complex system where neurotransmitters are generated in places very far from it.

As an example: it seems a fundamental impulse for long term memorization is a systemic (blood-stream) neurotransmitter produced by cardiac ganglia; other parts of "reward system", essential for learning, are connected to various parts of our body, including adrenal and intestine ganglia.

  • $\begingroup$ Good answer ZioByte. Althogh i disagree with the not possible aspect of it, i like to see it as we are not near scientifically evolved yet. $\endgroup$ – Jon Frank Aug 31 '17 at 2:31
