No, it's not.
And, BTW, what does *physics* mean?
It means our brains think, feel and dream by means of a biological computer (our brain). What substance: silicon or amino acids is beside the point. There are already billions of living computers walking the earth. They just use a different manufacturing process than humanity has harnessed and controlled.
Humans are alive.
"A virtual 1:1 molecular simulation of an existing human brain" is not.
Just a little tiny difference.![]()
We don't even have a definition of life. It's thinking like that, that will bring on one of the greatest genocides ever committed on this planet. It was once thought that blacks, jews, neighboring tribes and women were also subhuman. Some even suggesting that they had no souls nor were human.
It's that kind of attitude that continues to lead to the abuse of other primates because they haven't been supposedly sanctioned by God as worthy of rights despite exhibiting incredibly sophisticated and comparable intellect to small children.
A definition of life is largely impossible. Any definition we attempt to pin down is full of contradictions. It's an arbitrary definition. It doesn't actually really have a cut off point either. You can say that a human is obviously more independent and autonomous than a rock. That as an identified entity it would be more 'lifelike' than a rock.
Similarly humanity is not a binary experience. Some humans are 'more human' than others. Someone in a vegetative state with no brain activity is awarded human rights. A Dog is not. The Dog is "More human" than a vegetative human. Someone with developmental disorders and the intelligence of a 1 year old will never be as intellectually or emotionally sophisticated or advanced as a chimpanzee and yet we award the human rights but not the chimpanzee. It's a rational position to take. It's too dangerous to create a loophole in the legal system where humans can be deemed 'inhuman' but I think it's also a challenge to evaluate all life on a consistent set of rules and not based on their DNA, Chemical composition or other arbitrary and largely irrelevant details.
The reason I say everything is physics is because there has never been any proof or even suggestion of evidence that any thinking or deciding happens outside of our brains. On the contrary all of the evidence we collect on the human brain points strongly to all thinking being present inside of the chemical hardware running in our skull.
Yes, but would it's ignorance make it alive?
Brain input from the body is needed from both chemical and nervous pathways for the production of self-consciousness.
And yet people have cochlear implants. Blind people have had sight restored by neural implants. Both of these senses have been replaced by silicon implants. Quadrapalegics feel nothing below their neck. Creating a simulated skin and eyes and ears as part of the "brain on a chip" experiment wouldn't be challenging at all if we had the technology to simulate every atom in the brain.
We're all squishy robots.
