xenotux commented on The contrarian physics podcast subculture   timothynguyen.org/2025/08... · Posted by u/Emerson1

I have written previously about Sabine. I think it's fascinating to follow her trajectory. Initially I quite liked her show and my impression was that it gave valuable insights and critique of some branches of modern theoretical physics.

At some point I noticed that her shows were starting to significantly diverge from her area of expertise and she was weighing in on much broader topics, something in her early shows she often criticised scientists for ("don't think because someone is an expert in A that he can judge B").

At some point she weighted in on some topics where I'm an expert or at least have significant insights and I realised that she is largely talking without any understanding, often being wrong (although difficult to ascertain for nonexperts). At the same time she started to become more and more ambiguous in her messaging about academia, scientific communities etc., clearly peddling to the "sceptics" (in quotes because they tend to only ever be sceptic towards towards what the call the "establishment"). Initially she would still qualify or weaken her "questions" but later the peddling became more and more obvious.

From what the article writes I'm not the only one who has seen this and it seems to go beyond just peddling.

> I think it's fascinating to follow her trajectory.

I think it's a lesson that we all consistently fail to apply to ourselves. It is so pervasive on social media - HN included - yet it's something we only attribute to others. Our hot takes on quantum physics, molecular biology, and economics are always reasonable and rooted in keen insights.

It happens for a reason. There's something deeply satisfying about being a contrarian: the implication that you're smarter than the masses. It's usually hard to be a contrarian in your primary field of expertise. It's a lot easier to be a contrarian in someone else's.

What's the point of surveilling the movements of average citizens' money? They usually don't hide anyway. I suppose tax evaders were the target all along, with a smattering of criminal operators, e.g. drug dealers. Terrorists were but a pretext to produce moral panic.

The most important is taxation. People pay their babysitters or gardeners under the table, or transact with friends and family without reporting income, and this is a huge amount of lost tax revenue.

Another reason are policy options. For one, there are certain decidedly "non-terrorist" goods and services that the government might not want you to purchase. Heck, in the era of ZIRP, many economists were seriously talking about negative interest rates. You can't do that if a person has the option of taking out cash and hiding it under the mattress.

> The bots will eventually be indistinguishable from humans

Not until they get issued government IDs they won't!

Extrapolating from current trends, some form of online ID attestation (likely based on government-issued ID[1]) will become normal in the next decade, and naturally, this will be included in the anti-bot arsenal. It will be up to the site operator to trust identities signed by the Russian government.

1. Despite what Sam Altman's eyeball company will try to sell you, government registers will always be the anchor of trust for proof-of-identity, they've been doing it for centuries and have become good at it and have earned the goodwill.

Eh? With the "anonymous" models that we're pushing for right now, nothing stops you from handing over your verification token (or the control of your browser) to a robot for a fee. The token issued by the verifier just says "yep, that's an adult human", not "this is John Doe, living at 123 Main St, Somewhere, USA". If it's burned, you can get a new one.

If we move to a model where the token is permanently tied to your identity, there might be an incentive for you not to risk your token being added to a blocklist. But there's no shortage of people who need a bit of extra cash and for whom it's not a bad trade. So there will be a nearly-endless supply of "burner" tokens for use by trolls, scammers, evil crawlers, etc.

Note this is oxygen assisted - the diver breathed pure oxygen and (from the article) can increase available oxygen from 450mL to 3L in doing so.

Still impressive nonetheless and I didn't know that this trick is sometimes used in Hollywood to extend underwater filming time. Avatar 2 comes to mind when I was impressed to find out Sigourney Weaver trained to hold her breath for 6 and half minutes in her 70s!

Coming back to the article, I'm disappointed that the details were sparse - how do they check whether the contestant is conscious? How does the contestant know what his limits are before passing out?

Another factor is that it's easier to do it underwater than on land. The mammalian diving reflex is what helps.

Then why hasn't it yet? In fact, some lower-wage countries such as China are on the forefront of industrial automation?

I think the bottom line is that many Western countries went out of their way to make manufacturing - automated or not - very expensive and time-consuming to get off the ground. Robots don't necessarily change that if you still need to buy land, get all the permits, if construction costs many times more, and if your ongoing costs (energy, materials, lawyers, etc) are high.

We might discover that AI capacity is easier to grow in these markets too.

> I think this is similar to AI generated images: it puts a new creative tool in the hands of people who might have had good ideas, but didn't have a mastery of the medium.

Reading this sentence reminded me of the classic HN position of "ideas are worthless, what matters is the execution", usually mentioned in the context of an "ideas person" looking for their "technical cofounder" and the ideas person thinking they deserve at least 50%, often more, of the ownership of what would be built because without them there'd be no idea.

> if you had a great idea for a sci-fi story but no talent for writing, and if an LLM let you realize your vision, that's neat.

If your "vision" is only the "idea for a sci-fi story", is that really a vision? Good books leave the reader changed/influenced in some fashion, through the way the idea is presented and developed over the course of the story, not just from a blurb on the book jacket.

> overall, more creativity is hardly a bad thing.

Is coming up with an idea for a for a sci-fi story the meat of creative act such that that flooding the market with ideas counts as an increase in creativity overall?

xenotux · 6 days ago
I think that's an odd way of viewing creativity: unless you can pull off the whole thing, you're not really creative/

What about people who are not native speakers? Who are dyslexic? Do we deny them the spark of creativity because they can't write perfect prose without help? Heck, what about most sci-fi writers? Their editors often do a lot of heavy lifting to make the final product good.

If you have a killer idea for a meme or a really clever concept of a four-panel comic strip, but don't know how to use Photoshop or can't draw very well, is it a sin to ask a machine to help? Is your idea somehow worthless just because you previously couldn't do that?

I'm not disputing that a lot of people don't use these tools this way. In fact, that was exactly my point. If your "idea" is to crank out deceptive drivel, I'm not defending that.

I think this is similar to AI generated images: it puts a new creative tool in the hands of people who might have had good ideas, but didn't have a mastery of the medium. In that respect, it's cool: if you had a great idea for a sci-fi story but no talent for writing, and if an LLM let you realize your vision, that's neat. It has some negative externalities for the craftsmen, but overall, more creativity is hardly a bad thing.

The real problem is that the most lucrative uses of the tech aren't that. It's generating 10,000 fake books on Amazon on subjects you don't care about. It's cranking out SEO spam, generating monetizable clickbait, etc.

“Intel recommends an anti-static mat and a grounding wrist strap when installing a processor to avoid the danger of static electricity, also known as Electrostatic Discharge or ESD.1”

You know back when I built my computers, not once did I ever use any kind of static electricity discharge “system”. No wrist strap, no mat, no anything. And I don’t know anybody who did.

Has anybody ever actually destroyed a chip with static electricity?

(Of course it could be the climate I lived in as well)

xenotux · 6 days ago
Yes, although it's not very likely.

But keep in mind that final assembly and packaging is typically happening in large, air-conditioned halls with vinyl floors, conveyor belts, plastic office chairs, disposable coveralls, etc. There's more static zaps in places like that than in a home with wooden floors, reasonable humidity, and casual clothing.

And then, as Ken notes, there's the question of scale. If you statistically kill one chip in 200, you might not even notice that in a home lab. But for a manufacturer, that's more faulty devices shipping to customers than they want.

Absolutely, it's an old joke. But the fact that the thing even knew it was a joke and told it reasonably well... the bar is on the floor. (the one the guy in the joke walked into)
xenotux · 7 days ago
It's one of several canned jokes you get with a very high likelihood. Try a couple of times and be dismayed - you'll be getting the same three jokes over and over again. I'm fairly certain they were specifically tuned to return that. It takes special prompting to get it to write a new joke, and the results are typically disastrous / surreal.

That‘s one of the biggest health myths around. Cold weather does NOT weaken your immune system AT ALL (except if you‘re actually hypothermic, which is very different from just feeling uncomfortable). It’s the CONDITIONS that RESULT from cold weather that actually cause those infections to ramp up in winter (think more people staying inside in enclosed spaces).
