My thinking, tangential to the temporal section, is an Implementation Trilemma, a CAP style theorem. An implementation map can be: 1. instantaneous and faithful, at the cost of depending upon substrate-specific persistence parameters; 2. faithful and substrate-neutral, at the cost of requiring historical information; 3. instantaneous and substrate-neutral, at the cost of losing faithfulness. No implementation map can…

Instantaneous as in FTL?

An implementation map assigns computational states to physical states. It is instantaneous if its verdict for t is a function of physical state x_tau alone.

I believe machines could be made that think. But not purely digital ones. The brain most certainly isn’t a thinking machine precisely because it doesn’t have the luxury of unlimited time. Its design is not based on executing best algorithms, but rather finding good enough solutions among many time constrained but interlinked signal cascades. The brain and body instead construct time, a cohesive internal one,from the…

This is basically Christian apologetics. We've collectively thought we were special for so long that must now go through increasingly complex mental gymnastics to prove to ourselves that we are somehow uniquely sentient, despite increasing evidence to the contrary.

Special, yes, but mostly because we were expelled from the Garden of Eden. Our specialness is meant to be humbling.

Agreed. Well said. Trying to maintain that our mind is unreachable by the laws of logic is absurd. If reachable by laws of logic, then it can be stated. If it can be stated, it can be executed. Its funny that the very act of chaining sentences is what logic is. And every human thought can be written as a sentence.

> every human thought can be written as a sentence. No they can't. I have things in my brain that I don't have words for, that I'm able to find things other people have done to help me express them. You can attach sentences to music and art, but a picture is worth a thousand words. The thoughts on my head when I saw the latest Banksy, for example. Maybe I'm abberationally ineloquent, but I don't think I'm that except…

Yes they can. Retreating to "I feel things I can't say" arguments that cannot be falsified is a cope.

Either that or you didn't put effort into writing it down or you lack the capability to do it.

You can even write sentences like "cows have wings and smells green". Regular thoughts are feeble by comparison in terms of complexity.

Claiming "a picture is worth a thousand words" may work out in family gatherings but irrelevant and meaningless in a computation discussion. Picture is represented by concrete symbols.

That's not going to work: https://vod.video.cornell.edu/media/1_sfv907qp Conscious agents are creating spacetime. Not the other way around: https://pmc.ncbi.nlm.nih.gov/articles/PMC4060643/

Is this a misunderstanding of what the double slit experiment actually means, or am I misinterpreting it? If this is based on the idea that reality changes strictly as a result of a conscious observer existing and it is somehow related to consciousness, etc, that is not accurate. I learned this years ago from Philip Ball, one of the editors of Nature. There have been other scientists helping to clear up the confusion…

Well, Nima has shown that space-time is emergent from higher geometry like he amplituhedron and is not the fundamental basis of reality. Then Hoffman suggests that conscious agents could plausibly be the substrate through his category theoretic work. It's not a misunderstanding of the double slit experiment. (I think that was a talking point for a long time amongst hippies.) The interpretation that wave function collapse requires a conscious agent would be consistent with this idea though, and also consistent with simulation theory.

Just as the amplitudes program suggests that spacetime itself may be an emergent structure rather than the fundamental substrate of reality [1], the computational theory of mind may be mistaking an emergent representation for the source of consciousness. A more fundamental theory must therefore treat neural computation as an emergent interface within conscious-agent relations, rather than as the mechanism that genera…

I can prove things are the way they are outside my mind's perception of them, through the use of extra sensory devices. Even in a Donald Hoffman esque icon:hardware situation - and I think he said - "I don't take the icon literally, but I do take it seriously " meaning that even though it's an illusion, it still performs the function, I have trouble with mind preceding matter. It's the same trouble I have with human-…

Nima is a theoretical physicist and many of them have diverged away from hard science. Hard science needs to connect and relate back to classical physics mathematically and ideally have a way of being tested. Not all theoretical physics ever gets there, probably most don't. The best adjusted theoretical physicists are aiming to expand on our understanding of classical physics which we know to be useful and true to the best of our knowledge as opposed to coming up with entirely new untestable theories of physics that are themselves based on top of untested theories.

Psychology is also a soft science, so while clinical psychology can be useful when it is grounded in real instances of human behavior, theoretical psychology is on the softer end of an already soft spectrum of science.

Simulation theory isn't very convincing and it's really just the opposite end of the spectrum of people demonstrating proof of god. Both types of arguments are almost universally logically flawed. It doesn't prove or disprove them, it's just bad logic.

You hypothesize that a merger can fail when it's supposed to succeed? But the merger is a part of computation, so if it's required by computation, then it shouldn't fail, otherwise computation is not implemented.

Indistinguishability of merging states: π(x)=π(x’’)=q

Continuation during merge: δ(q,i)=δ(π(x),i)=δ(π(x’’),i)

Having an internal representation doesn’t imply an English sentence exists. Temple Grandin's written about "thinking in pictures". Language is lossy. For a doctor, the question, how much does it hurt, on a scale from 1-10? is the best we can do.
