I agree that we can’t reject the hypothesis that reality is continuous (and, even if spacetime turns out to be discrete, it seems hard to imagine that the amplitudes of the wavefunction(s) have finitely many possible complex values, though I suppose we can’t rule it out) I disagree that this necessarily implies any difficulty for the possibility of brain scanning and AI. Just as things sampled faster than the nyquist…

Argument: 1) Intelligence requires being spatiotemproally acting-on and being acted-on by a spatiotemporally dynamic environment. 2) Dynamical spa'temp properties of the body enable (1) 3) These properties are continuous features of the bodily (eg., organic plasticity) 4) continuous properties are irreducible to measurably discrete ones 5) computers are systems which we build that have measurably discrete systems the…

I don’t think claims 1 or 4 are justified (where claim 4 is interpreted in the relevant sense), and I’m not sure quite what you mean by claim 2.

Who says neural networks aren't in pain when their fitness (reward function) is subtracted from? or happy or orgasmic when the function is bumped up? Pain/pleasure seem to have easy enough analogue to at least something like a reward function, but what really gets me is colors. I feel like if honestly considered, the word "color" is all that's necessary to disprove materialism. Color is. How? Dunno.

Perceptions and feelings are real as you both experience them and could measure their signals in the brain, if you would have the proper tech to do that. And filtered, processed perceptions exist as well. In a "pipeline" in some brain - no matter if biological or artificial - somewhere in the middle you have processed signals of sensor input that have a complex meaning that has only some relation to the actual physic…

Would this be a good compression tool in any instances?

In the paper you find a link to a GitHub repo that should have all results being reproducible

And here is the relevant notebook for animal shapes: https://github.com/Ranlot/single-parameter-fit/blob/a065af75...

Epic, thank you:)

Space time is something that appears to you, the obsever, and only to you. There is no universal shared perception of anything or any event and therfore no common "reality" to try and suss out. It is quite likely (rather obvious, really) that what we call reality is continuous in design, infinite in abstractions, relationships, and descriptions, yet at the same time cohesive in a single entity. Those type of systems…

>therefore no common "reality" to try and suss out.

You or I may be wrong about any specific aspect of reality, or fail to be aware of it.

However, we can be sure there is such a thing.

"Reality is that which, when you stop believing in it, doesn't go away." (Philip K. Dick)

It's kind of like the concept of agnosticism.
