One of those things about claims of “AGI” is that to really build a human-like intelligence we’d have to simulate a human brain as whole because 1. it’s the only thing we know that produces human intelligence and 2. no one knows how it actually works.
Because of (2) it’s irrelevant what anyone says about LLMs or any other technology (with the exception of simulating a whole brain)—you can’t know if a technology is intelligent like a human because we don’t know what that means or how that works.
Fun thing, it turns out it’s impossible to simulate a whole brain with the resolution required (basically quantum physics level), and you’d have to emulate a chemical and physical environment for the brain as well (it will also need a body etc.).
You’d also have to simulate other humans with brains from which the brain can learn; but to simulate those you’d have simulate evolving humans from single-cell organisms first etc etc ad infinitum

Light Streaks — generative photography
A small selection of long-exposures of randomly generated IFS (aka Iterated Function Systems), a family of very oldskool primitive/trivial fractal functions, but which can produce a fairly wide variety of outcomes. Each image is the result of billions of iterations of a single particle being iteratively transformed (meaning the particle's current position is used as the input for computing its next position etc.) For each iteration & posit…

skinnylatte@hachyderm.io - So many people here are like, oh I wish I could move to (another country, that is also having a hard far right turn, and anti-immigrant horrors, just in a language they don’t speak)
It’s totally fine to feel you need to get away for safety and yes white cis Americans will likely face less of a threat in many places
However
I’m so irritated by the pretense that all of the current problems in the world are limited to US borders. We are going through a rough time of it.. but a lot of these problems are structurally global. ‘America is the worst’ is also a form of American exceptionalism.

Abrupt Gulf Stream path changes are a precursor to a collapse of the Atlantic Meridional Overturning Circulation - Communications Earth & Environment
The northward shift and rapid displacement of the Gulf Stream provide an indirect early warning of Atlantic Meridional Overturning Circulation weakening and collapse, revealed by both high-resolution ocean simulations and historical observations.

Abstract: This paper presents experimental validation of the homogenized harmonic balance finite element method (HomHBFEM), which we have developed as a dedicated simulation technique for magnets with fast excitation cycles, in particular the fast corrector (FC) magnets for PETRA IV at DESY. The HomHBFEM allows efficient three-dimensional nonlinear eddy-current simulations of laminated magnets at elevated frequencies with a relatively coarse finite element (FE) mesh and without computationally expensive time-stepping. This is achieved by combining a frequency-domain-based homogenization technique with the harmonic balance FE method. The simulation results for the magnetic flux density along the axis of the FC magnets as a function of frequency and the resulting integrated transfer function (ITF) are compared to Hall probe and search coil measurements of the first prototype FC magnet for PETRA IV. A good agreement between simulated and measured ITFs is achieved for excitation frequencies from 10 Hz to 10 kHz.

If you’re in any way surprised by this you clearly have no idea who Jimmy Wales actually is.

A tl;dr version might be, that no physical system can exist outside the universe, which for the purpose of measuring it is not finite; therefore no physical system can be simulated with arbitrary accuracy.
