Saving a body
The essence of each one (our soul and what makes us living beings) is something that belongs and is created by God, whom promises salvation and benefits for good acts. We will never get to complete any endeavor in decoding or creating something analogous to our soul.
However, saving the brain in a non decaying body is interesting and a productive subject, which takes us to a fertile area for concrete and non-schizoid thoughts.
- Identify each signal that enters and exits the brain. Basically everything that comes in and out and is easily indentified by some specialized technology we might or might not have at the moment (I have NO idea how far we are advanced in this area).
Decode the signal so that it is reproducible. Place of origin, how it was originated, destination and way of acting in the destination place (remembering that we are going to have to create artificial bodies too)
how: you have to know how to decode a nervous signal. Depart from there.
all tests must be non-invasive (we have to develop the technology, this is for those that like science and are willing to take part on a very hard biotech, long term and high reward project)
all tests must be generalist, and sub-species that we might find (cause of our origin) must be drawn from studies of the brain’s logical code.
Only resort to invasive stuff when the project is VERY evolved and pain is no longer a real problem given studies on how pain works (how to achieve and study-focused processes on a brain without having to deal with any sort of it)
Final part (decades from now)(just to give some scare on you, reader) = remove the brain and weld on the artificial housing.
Have a nice trip.
