So @FCfromSSC, you've stated that you consider a lack of aliens, a lack of AGI, and a lack of Read/Write Consciousness upload ability to be proof that humans are divine and that God exists. If we find alien life, create AGI, and can scan a human brain and make a copy, would that be proof for you that God doesn't exist? Would any of those events change you mind?
He explicitly stated that if we could Read/Write minds then he’d change his mind.
I don't see that specific statement in there. Interesting discussion though. I think a more accurate phrasing would be:
If Free Will truly does not exist, it should be possible, if we were able to gather sufficiently detailed information about an individual's brain, to predict with 100% accuracy everything that person would think, say, and do, and this could be done for any individual you might choose.
The ability to read and write minds does not necessarily prove determinism or disprove free will. It does seem likely though that, if we were ever able to do such a thing, the details of how that process worked would give us considerable insight on those subjects. We can say now that it's still possible that free will doesn't really exist, but we don't have sufficient technology to gather detailed enough information about anyone's brain to fully predict their behavior. If we were able to reliably read and write minds, it would be very tough to say we just didn't have sufficient information. At that point, either we would be able to predict behavior and prove the determinists right, or we would still not be able to fully predict behavior and that would prove that free will actually does exist and the determinists are wrong.
I feel obligated to also note that pure determinism leads to some rather dark conclusions. If it were possible to scientifically prove that a person would 100% only do negative and harmful things for the rest of their life and it was not possible to change that, what else would there be to do except eliminate that person?
Well we know that this isn't a possibility, right? The Heisenberg uncertainty principle prevents us from modelling anything with that degree of accuracy even in theory. Even if it were possible to take a fully-scanned human and simulate their future actions, it's not possible to fully scan that human in the first place.
If we did understand people that well though, I think the correct approach would be to offer the current person a choice between an ineffectual future, where they retain their current values but without the ability to harm others; and a different one, where their personality is modified just enough to not be deemed evil. This wouldn't even necessarily need physical modification--I doubt many scanned humans would remain fully resilient to an infinite variety of simulated therapies.
That isn't how Heisenberg's Uncertainty Principle operates except in thought experiments and sci-fi episodes. The actual principle deals with the dual nature of phenomena like a photon, acting as a wave until you can pin down the location, then you lose the wave information and gain the location information. It also only operates on the most microscopic scale imaginable, your keys are always going to be where you left them.
Any object, even as small as neuron is not going to be impacted by this principle; containing 100 trillion atoms and some multiple of that I can't calculate without getting into moles for various elements in actual singular particles, it is a statistical impossibility for any quantum strangeness to impact even one brain cell. Not to mention that there are around 170 billion cells in the brain (neurons/Glial cells).
So 18 (carbon)* 100 trillion* 170 billion =3.06e+26 or 306,000,000,000,000,000,000,912,784 particles in the brain.
Even if it could impact your thought process (which it mathematically can't), then your actions would be random, not "free will", worse than deterministic I should think.
I think this is misleading. You can't know a particle's position and momentum with certainty, period. This applies to all particles, not just photons and other particles commonly understood as wave-like, since fundamentally all particles are wavelike. We can't actually perfectly predict the behavior of a single particle, let alone an entire brain.
We're talking about perfectly simulating the human brain. Anything less than perfection will lead to errors. If only a single atom in the entire brain were off in your scan by a planck length, your simulations would be inaccurate, especially over long timescales, due to the butterfly effect. But in this case every single atom in the brain will be off by more than that.
It's debatable whether quantum physics is actually contradictory with determinism, but aside from that, I don't see why randomness is any worse than determinism. Either way our actions are ultimately governed by external forces.
Well, this is a thought experiment after all.
I think it is a fundamental misunderstanding of the materialist position to call these external forces. Your mind is the processes in your brain, these processes not violating the laws of physics doesn't make them external.
The counterargument is that your mind was created by purely external forces, so even if "you" are making decisions as of the present, you never got to choose who the "you" is that is making those decisions.
That said, I agree, I just didn't want to get into that when my point was more limited.
