To develop better brain-computer interfaces, we'll analyze and probe the brain so we can learn to communicate with it electronically. As cyborg technology develops, we'll be able to sustain the brain outside the body, as a brain in a jar; to interface electronics directly with the neurons of the brain. It's all part of the push for virtual reality. One day, we may even be able to siliconize the brain, to perform uploading.

We don't know yet what the technological challenges we have to oveercome before we can hold brains in jars; we guess it will become possible around 2025-2045. We will need to develop the following technologies first:

  • Feeding oxygen and nutrients to the brain through artificial blood.
  • Transplanting the brain into a jar of sorts.
  • Intercepting, intepreting and interfacing sensory inputs and outputs.
  • The ability to record signals is a natural predecessor to the ability to produce signals.
  • Simulating signals generated by the human body (autoperception) so that the brain doesn't freak out.

How would the brain respond if it didn't sense a heartbeat? How much intelligence lies in in body parts and how much is centralized in the brain? How much does the brain rely on the body?

We'll also have to convince governments to allow brain-body separation, in a situation where this is a reasonable course of action.
