ZhuanXia··on The world might run out of people (2019)
I was not intending to be antisemitic. I just think is a salient example of a religion that no longer believes in God. Christians tend to profess a belief in God right up until they become atheist, at which point they no longer attend church.

Then those resistant to conversion will be selected for.
ZhuanXia··on There’s No Fire Alarm for Artificial General Intelligence (2017)
You should not impute beliefs on others when you have not read their arguments. I would recommend reading this: https://selfawaresystems.files.wordpress.com/2008/01/ai_driv...
ZhuanXia··on Tesla Model 3 Drives into Overturned Truck in Apparent Autopilot Failure
Bear case for self-driving: in 1 million miles of driving, roughly the number between major human accidents, do we really think these cars will not encounter one AI-complete problem.
ZhuanXia··on Have the record number of investors in the stock market lost their minds?
A few years before I started working, I read Average is Over. Made a good case that labor power's decline would ramp up ever further. People like to poo-poo AI, but I have been following AI since the dark times before 2012. Winograd schemas, style transfer, GTP-2, image recognition - it is hard for people now to understand how impossible these tasks seemed at the time. The rate of progress is insane and it is foolish to bet against it.

Perhaps we are approaching a time where capital can be converted directly into labor in a way that scales. If this is the case the market is ridiculously undervalued, almost comically so.

I have maintained high savings rates and acquired capital ever since I read that book, regardless of valuations. I consider my portfolio insurance against this scenario.

ZhuanXia··on Fed Report Shows Magical Thinking on Safety of Wall Street’s Banks
I find monetary policy a hard subject to reason about. It is too complex for me to understand. Yet the political economy of it is such that I would expect the expert classes to be corrupted in some way. Still, I just act like I believe the experts have it under control. The phrase "epistemic learned helplessness" comes to mind.
ZhuanXia··on Ask HN: Intellectually simulating Podcasts/conversations/Talk
Julia Galef remains the best interviewer I have ever heard. She is so incredibly sharp. Her guests will make a point about an abstruse philosophical/economic/statistical topic and she will reply with a perfect, novel, challenging question that betrays an immediate understanding of the complex idea she just processed. Shame the show is on hold.
ZhuanXia··on ‘I Could Solve Most of Your Problems’: Eric Schmidt’s Pentagon Offensive
McNamara’s Folly is a great book on one of his more idiotic policies, and a great meditation on the dehumanizing cruelty that results from basing policy on false but ideologically pleasing assumptions.
ZhuanXia··on Ask HN: Intellectually simulating Podcasts/conversations/Talk
Physicist/geneticist Steve Hsu and linguist/neuroscientist Cory Washington have an extremely good podcast called Manifold. This episode in particular is a good introduction to the show: https://infoproc.blogspot.com/2020/04/vineer-bhansali-physic...
ZhuanXia··on Raku vs. Perl
I see. Just a c-style loop absent conditions. I find it kind of ugly for some reason.
ZhuanXia··on Raku vs. Perl
Not a Perl guy. What are the semicolons in that if statement all about?
ZhuanXia··on As YouTube traffic soars, YouTubers say pay is plummeting
I have seen a lot of shoddy statistics used by ad people to justify the necessity of ad people. I would trust a random engineer over the ad team for this task purely as a matter of incentives.

ZhuanXia··on Keeping the coronavirus from infecting healthcare workers
I have seen the progress in China since the late 1990s. A rate of change impossible for a modern westerner to believe. China is not a photograph but a video on fast-forward.
ZhuanXia··on Keeping the coronavirus from infecting healthcare workers
The shameful lies about masks not working for civilians will kill thousands. Evidence based medicine (over the modern Bayesian Science-based medicine) has paralyzed our health officials from making common sense calls off priors. Homemade masks appear to be reasonably effective. The official response should be to make some form of improvised mask required when out of home, and ration regular mask for health care workers.

Even a scarf made of a t-shirt over the nose and mouth will likely reduce RO when used at scale on the population. The best way to protect healthcare workers is to reduce the R0 below 1. Nothing else will help. Widespread use of homemade masks, though not tested in a double blind trial, is low risk enough and seemingly effective enough to encourage.

Countries enforcing widespread mask use have lower ROs.

ZhuanXia··on Manufacturer Threatens To Sue Volunteers who printed a valve
Patents are government-granted monopolies. Hardly a free market. Same with land ownership, hence my Georgism.
ZhuanXia··on $5000 per violation of price-gouging in CA
High prices induce production that would not have occurred otherwise. They also curve demand downwards so that only those who really want the item will get it. There is little reason to outlaw price gouging save for humans have a disgust response to people who profit from tragic events. Absent these laws, there would be incentive to create stockpiles of needed items before a disaster and retool less-efficient factories to produce now more-profitable items during a crisis. We do not think markets are magic. We think they are machines that run on price signals, and bashing these signals with hammers will degrade the efficiency of the machine.
ZhuanXia··on Dr. John von Neumann at the dedication of the NORD (1954)
The historical context for that statement is it was made when America had a monopoly on nuclear weapons and Stalin's Soviet Union, a dictatorship of incomparable authoritarianism and delusion, was on the cusp of developing such weapons. Few would have predicted that a nuclear war would not occur once that happened. Under these circumstances, a first strike followed by occupation may have been rational. And given the complete insanity, cruelty and dehumanizing brutality of Soviet policy in the following 50 years, it's possible American occupation of the Soviet union would have saved many lives on net. See East vs West Berlin, for example. His position on first-strike was not very irrational given what was known at the time. Even in hindsight, it is hard to say either way.
ZhuanXia··on Dr. John von Neumann at the dedication of the NORD (1954)
>Would this diminish our view of his legacy, for him to come "down to earth"?

I doubt it. Consider how the greatest minds of the 20th century thought of him:

"I have known a great many intelligent people in my life. I knew Planck, von Laue and Heisenberg. Paul Dirac was my brother in law; Leo Szilard and Edward Teller have been among my closest friends; and Albert Einstein was a good friend, too. But none of them had a mind as quick and acute as Jansci [John] von Neumann. I have often remarked this in the presence of those men and no one ever disputed me."

— Nobel Laureate Eugene Wigner

"You know, Herb, how much faster I am in thinking than you are. That is how much faster von Neumann is compared to me."

— Nobel Laureate Enrico Fermi to his former PhD student Herb Anderson.

"One of his remarkable abilities was his power of absolute recall. As far as I could tell, von Neumann was able on once reading a book or article to quote it back verbatim; moreover, he could do it years later without hesitation. He could also translate it at no diminution in speed from its original language into English. On one occasion I tested his ability by asking him to tell me how The Tale of Two Cities started. Whereupon, without any pause, he immediately began to recite the first chapter and continued until asked to stop after about ten or fifteen minutes."

— Herman Goldstine, mathematician and computer pioneer.

"I always thought Von Neumann’s brain indicated that he was from another species, an evolution beyond man."

— Nobel Laureate Hans A. Bethe.

In his final days, Neumann tragically lost his genius to brain cancer. His friend Edward Teller said this about it:

“I think that von Neumann suffered more when his mind would no longer function, than I have ever seen any human being suffer."

Gwern has a funny essay about cloning Von Neumann here: https://www.gwern.net/Embryo-selection#glue-robbers-sequenci...

As Neumann seemed to be god-like intelligent, highly personable, and very kind, if we were to clone any historical figure, he seems like a good bet!

ZhuanXia··on eBay bans sales of face masks and hand sanitizers to combat price gouging
Most services exist to ameliorate a want. That is to reduce misery. Your statement basically means people shouldn’t profit. But if they shouldn’t profit what incentive will they have to reduce misery? It seems clear to me that if anyone is guilty of profiting from misery it is doctors, whose high salaries are inexcusably tied to misery. Truly, they should donate their time and live in a tent outside the hospitals they work at, and accept only kitchen scraps for compensation.
ZhuanXia··on Coronavirus: the second-weirdest solution?
I feel like brass may be better, as it contains zinc and copper and does not oxidize as easily. How about an alloy of zinc, silver and copper?
ZhuanXia··on The Great Affordability Crisis
We have a legally entrenched doctors guild with a government granted monopoly on their profession. We have patents granting monopolies on chemicals and devices. This is not a free market. We have zoning laws granting landlords a monopoly on housing supply. Again, not free. All the modern equivalent of royal patents allowing the population to be farmed by the professions and the landed classes without competition. Hardly laissez-faire.
ZhuanXia··on What Is the Point of Universal Basic Income?
There is a notion in economics of complements and replacements. The plow was a complement to horse labour, while the gas engine was a replacement. The former increased demand for horses while the latter basicly eliminated it. If we truly had human-level AI, labour models predict human wages would decline below subsistence. However, applying these labour models in a regime where we have AGI makes little sense, as all that will matter for human welfare is the objective functions of the AIs.
ZhuanXia··on What Is the Point of Universal Basic Income?
>An AI revolution is not required to eliminate jobs.

Yes it is. If you have tasks that cannot be automated, people's labour will have value. It would require AI that is as good as any human, and that is cheaper of course, to eliminate all jobs. And even then rich people may prefer human labour for nostalgic or signalling reasons. Eliminating all jobs is a tall order.

ZhuanXia··on What Is the Point of Universal Basic Income?
In my experience automating tasks many highly educated workers are easier to replace than low-skill workers. Many a university grad has been made redundant by a Python script; 0 plumbers have. AI people have a term for this:https://en.wikipedia.org/wiki/Moravec%27s_paradox
ZhuanXia··on What Is the Point of Universal Basic Income?
If automation will truly do all jobs, then by definition we have human-level AI. As labour supply enormously limits economic growth, we would have economic growth that is unimaginably large in this scenario. Imagine how quickly a startup could scale if they could clone their best engineer. Now imagine that applied to the economy as a whole. We would get economic doubling times on the order of months. If we truly get automation as flexible as any human, economic growth would be truly insane. Even mild redistribution would be effective in such a scenerio.

Absent human-level AI, there will remain tasks that only humans can do. Hence we will have jobs.

But truly, if we do get human-level AI, it seems to me we will have bigger problems than unemployment. I hate to get all Nick Bostrom, but it really does seem like the objective functions of the machines would be all that matters in this scenerio. As it is their objective functions, not laws, that would decide our fate. Either human-level AI is far off, in which case technological unemployment is not a worry, or it is not in which case technological unemployment is the least of our worries.

ZhuanXia··on I had to get a background check for my job; the report is a 300 page pdf
It's basically an algorithmic filter for wokism. A lot of innovative people tend to be unswayed by our strange moral fads. Seems like talent is being left on the table. Good news for startups.
ZhuanXia··on A Proof of Useful Work for Artificial Intelligence on the Blockchain
It strikes me that is can still be useful, it just has to produce a good whose value cannot be internalized. It would need to be a perfect public good. Can’t think of any examples though.
ZhuanXia··on SpaceX tests black satellite to reduce ‘megaconstellation’ threat to astronomy
Astronomers will have to get used to this. If we ban these for such nonsense reasons, it will be Chinese satellites blocking their view.
