Assuming that what we define as conscientiousness is just the way neurons connect to each other and the content of these neurons then as long as the neurons don't die your conscientiousness, personality, identity should not be altered.

That also means the the brain could be copied and we could be able to preserve people's conscientiousness.

How cool would it be if after you die you would still be able to exist as part of a vast network of interconnected brains able to manipulate virtual reality.

Who need AI when you could just upload yourself :)

Edit: Or you could clone yourself which is where it gets a bit weird since a clone would not be you and left to its own devices it would develop it's own conscientiousness, personality, identity however what would happen if you imprinted your neural pattern onto the clone.

Would that be a new person or just you in a new body.
