Consciousness Does Not Die
The groundwork for this new technology requires us to accept that consciousness exists outside the brain. We are not our bodies, we are conscious beings--This means that we don't die. Our consciousness simply exists outside our physical bodies and moves on to a subtler plane of existence. Those who have 'died' are still with us, they are just not visible to us in our waking state.
If we can accept the idea of eternal consciousness, it is not a stretch to believe in the existence of deities, interdimensional beings, and other non-physical entities. With 'Spirit' no longer being an abstraction, we can begin to de-mystify the so-called subtle realm of existence and understand that everything boils down to consciousness. Therefore, consciousness is the point of control for future technologies, and devices can be powered through a consciousness-controlled interface.
The survival of consciousness outside of the brain has been well-documented by numerous studies, including by the University of Virginia, even if it is not yet a commonly-accepted idea. I believe that history will prove the acceptance of this fact as the new 'Earth is Round' paradigm.
