> Time doesn’t exist. Do the people writing this garbage live in a vacuum? Is it AI slop?

Maybe don't dismiss an idea as garbage before trying to understand it.

One of the ideas here is that time is an emergent phenomenon, like how temperature and gas pressure seem real at a macroscopic level, but disappear once you look closer. They simply describe the average kinetic energy of all the molecules in the area.

The _hypothesis_ is that time could be similar.

This obviously seems silly in hindsight. Warnings about radium watches or asbestos sound less silly, or even wise. But neither had any solid scientific studies showing clear hazard and risk. Just people being good Bayesian agents, trying to ride the middle of the exploration vs. exploitation curve.

Maybe it makes sense to spend some percentage of AI development resources on trying to understand how they work, and how they can fail.

Animals eat their disabled children. Humans should also do it then, since it's normal or natural.

Around 100k people die from age-related disease every day. I'd be careful to dismiss that as not a problem.

luc4sdreyer··on S1: A $6 R1 competitor?
That is assuming the accelerating AI stays under human control.

We're racing up a hill at an ever-increasing speed, and we don't know what's on the other side. Maybe 80% chance that it's either nothing or "simply" a technological revolution.

luc4sdreyer··on 20 Years of "Not Even Wrong"
> He is critical of string theory on the grounds that it lacks testable predictions and is promoted with public money despite its failures so far,[1] and has authored both scientific papers and popular polemics on this topic. His writings claim that excessive media attention and funding of this one particular mainstream endeavour, which he considers speculative, risks undermining public faith in the freedom of scientific research. His moderated weblog on string theory and other topics is titled "Not Even Wrong", a derogatory term for scientifically useless arguments coined by Wolfgang Pauli.

> but it will require paradigm shift, so there will be a lot of resistance before revolution.

I think the main point of resistance is the incompatibility with observations. All Tired light models have been falsified: https://en.wikipedia.org/wiki/Tired_light#Specific_falsified...

If you're aware of a model that can fit some or all of our observations, please share it!

>from one point in space

- We have multiple observatories on and around the planet - The Earth is moving around the Sun - The Sun is moving around the centre of the galaxy - The galaxy is moving towards the great attractor, etc

The Copernican principle states that humans, on the Earth or in the Solar System, are not privileged observers of the universe, that observations from the Earth are representative of observations from the average position in the universe. This has been tested in various ways: https://en.wikipedia.org/wiki/Copernican_principle#Tests_of_...

A nice PBS spacetime video about the topic: https://www.youtube.com/watch?v=q-6oU3jXAho

You can also ask how do we know that the laws of physics haven't changed over time. We don't. But at some point you have to make a few basic assumptions in order to have any hope of making scientific progress.

In the 3rd century BC, Aristarchus calculated that the Sun was between 18 and 20 times farther away from the Earth than the Moon, and proposed the Heliocentric model as a result. The true value is instead approximately 400 times. But it's incredible given that he didn't have lenses, the value of Pi, and that the Geocentric model was considered correct until 1800 years after his death.

luc4sdreyer··on On the Double-Slit Experiment and Quantum Interference in the Wolfram Model (2020)
>If known programs cannot run on this new OS then it is defective.

I understand the problem is that, like String Theory, this framework has a practically unlimited supply of variables that can simply be tuned to fit existing experiments, while not offering any way to be tested.

luc4sdreyer··on On the Double-Slit Experiment and Quantum Interference in the Wolfram Model (2020)
This is from four years ago, and there are some comments on the article by Matt Kelly that show that the "interference pattern" is just an artefact. The author did not respond despite several requests to do so.

luc4sdreyer··on Elon Musk: "Don't advertise. Go f*** yourself"
Agreed. I'm actually interested in a discussion about his mental health.

A change in behaviour towards irrational aggression could be due to extreme stress, lack of sleep, drugs, a brain tumour, bipolar disorder, etc.

My questions:

1. Has his behaviour changed, or has he always been this unstable?

2. Are there any evidence of health problems?

luc4sdreyer··on Sam Bankman-Fried is going to jail
The term became very popular during Ethan Couch's trial, because the judge bought it.

> Couch was indicted on four counts of intoxication manslaughter for recklessly driving under the influence. In December 2013, Judge Jean Hudson Boyd sentenced Couch to ten years of probation, subsequently ordering him to undergo therapy at a long term inpatient facility. Before sentencing, Couch's attorneys had argued that Couch had "affluenza" and needed rehabilitation instead of prison, arguing that Couch had no understanding of boundaries as his affluent parents had never given him any. Couch's sentence, judged by many as outrageously lenient, set off what The New York Times called "an emotional, angry debate that has stretched far beyond the North Texas suburbs".

I'm not aware of anything concrete by OpenAI, but others have offered possible explanations.

One idea is that the cause is batched inference in sparse MoE (mixture of experts) models.

They claim 1.1x to 7x, depending on what you're doing. The 10% to 50% is for the ~10k GPU LLM training, where the main bottleneck tends to be networking:

> DGX GH200 enables more efficient parallel mapping and alleviates the networking communication bottleneck. As a result, up to 1.5x faster training time can be achieved over a DGX H100-based solution for LLM training at scale.

> Scientific research typically has been founded on high ethical standards established by researchers in academia and health care research institutions. Scientific fraud, an act of deception or misrepresentation of one's own work, violates these ethical standards.

And according to Ken Schutte:

Can anyone make the case that these two descriptions don't overlap? Personally I can't see how the original author can be so blasé about this.

I don't want to support this idea because it goes against my worldview as an atheist from a very conservative society. I grew up on Hitchens and Dawkins.

But the YouGov poll [1] that the WaPo article is based seems to support this idea: 30% of Agnostics answered yes to the following question: "Do you believe in astrology, or that the position of the stars and planets influence people’s lives?"
