there is an even bigger problem with this attitude than has been expressed, it's amazing to me how people dont seem to grasp this. Consciousness is not software running on hardware. The brain is not a computer. You cannot "upload" your consciousness, nor do we have any reason to believe that consciousness would even function in any way similar to what we have now when seperated from the body.
Firstly, The mind is not located in the brain. Just as one example, the bacteria in your gut secrete hormones which influence your thoughts (https://www.nature.com/articles/nrn3071
for more information research "gut-brain axis"). That's not to even mention the rest of your body, your immune system, vascuar system, limbs etc etc.
Secondly, the brain is not an electrical system. It is an electro-chemical system, and likely more chemical than you think. Uploading your brain makes about as much sense as "uploading" your liver, or heart. The only way to do it would be to physically model its entire operations, and even then, a simmulated heart wouldn't be of much use. We have no reason to believe that the same wouldn't apply to the brain.
Thirdly, the brain is not a computer. This is one of my pet peeves. The "computer" model of the brain is a METAPHORE. Not an accurate description of consciousness.

If it were possible, that would be great. But unfortunately, the entire science fiction concept is based on missunderstandings and half truths which serve to tell good stPost too long. Click here to view the full text.
