handle584··on BYD doubles its Brazil market share to 9.7% a year after opening its local plant
Slave-like by American standards maybe, not Chinese. In the US Janesville GM pays assembly workers $28/hr in 2008 before closure, and nowadays anywhere between $20-$35 and they enjoy a strong union and good pension.

A few labor lawsuits show that in China Tesla wage starts at ~$4.5/hr while BYD ~$1.7/hr. Tesla also limits overtime to 36 hrs/mo by China labor law, while gov allows BYD workers to clock 441.5 raw hours in a single month. Pension and union is basically non-existent. And the reason why ppl work at BYD instead of Tesla is by clocking monstrous overtime they actually make more despite lower hourly pay.

There are reasons why Tesla consistently ranks in China 1st/2nd by sales. One of them is Chinese workers are the ones exploited by sweatshops and a government only nominally communist so they are paying the price, while Western customers are enjoying good ol' NIMBYism.

There is a lawsuit in China involving BYD, it shows in October of 2020 an assembly line worker clocked 441.5 raw hours, got paid ~$1.96/hr after overtime multiplier. The reality in car manufacturing in China is 12hr shifts, 2 days off a month and $2-3/hr wage, simply sweatshop in the 21st century.

BYD pulled off the same thing in EU as well, in Hungary [0].

The dark factory part is simply propaganda, the viral WSJ interview is only about body assembly which is already automated everywhere. The labor intensive part is the general assembly and even they admit this in the video. However here it's like Chinese EV found the silver bullet in car manufacturing.

> some tech companies

Actually most, programmers have protested a few years ago to no veil. The movement is called 996.icu if you are interested, and they complied lists of companies that run 996 schedule and the normal 955.

> the government is somehow imposing this on every single worker

Of course not, the gov with communism in its name is simply not enforcing their own labor law and cracking down labor movements.

Pretty spot on for most urban ppl, a few comments

- Private insurance is always up to one's own, very few employers provide this.

- If young, your parents or yourself have to pay for coverage until you graduate, otherwise no coverage.

- If elderly, depends on your employment history. To qualify, your employers have to contribute continuously for decades and it's tied with social security. Otherwise you are on your own.

- If working age but no job, similar to being young you have to pay.

Pretty sure OP meant mainland China only, excluding Hong Kong, Macau and Taiwan.

Easy or not is hard to argue, but more foreigners live in Taiwan than the whole mainland China.

handle584··on Sharing AI progress in mathematics
1896 PNT is basically 1859 Riemann + a trig inequality.

1830 Dirichlet's result is qualitative only, it shows infinitude but not the asymptote in terms of the zeros for it predates Riemann.

To me this is the first substantial step after the 1896 PNT, and we really do not see much progress in the whole 20th century. Personally so far there are only two people worth mentioning,

- Euler, introduces the real zeta function and Euler product, establishes the functional equation at (half?) integers.

- Riemann, introduces complex analysis ideas to the zeta function.

And of course this result if it is true. This is first to penetrate the critical strip, which nobody had any idea how to approach for over a century and a half.

handle584··on Neijuan
Overworked Chinese workers have been making western consumers better off for more than two decades now. Chinese domestic consumption is very low even among developing countries, negligible compared to its gigantic export.

Upon joining WTO one prerequisite is 5 days-8 hours work week, while presently in China you often find 996 schedule instead, with factory workers even worse with 12 hour shifts and 2 days off a month.

It is simply sweatshop in the 21st century again, a hallmark of Neijuan.

handle584··on Starbase, LA
> It was the most sold during March, but that's it.

Also June, and a better link for monthly sales by model from your source is https://www.autohome.com.cn/rank/1.

Basically Model Y has been consistently in top 3 by monthly sales of EV in China so far in 2026. If you count by 3-month or 6-month periods, it is only next to Geely EX2 at 1/3 of its price as pointed out by another comment.

Part of the fluctuation is due to one month of every quarter the Tesla Shanghai factory is oriented at export, so domestic number drops dramatically.

HN is full of ppl claiming Chinese EV is superior in every way without realizing that Tesla is incredibly popular in Chinese domestic market.

handle584··on Learning more about Claude's mathematical capabilities
The keyword is soon, so OP simply meant current generation of LLMs are not likely to prove RH, judging from the performance shown in the paper.

Why? Because such explicit numerical improvements are not that interesting, which is best summed up in a review paper [0] of our efforts on RH spanning a century and a half,

> The pathetic attempts to enlarge the ridiculous zero free region in the critical strip is a perfect example of what brute force can do without fully exploiting fundamental arithmetic aspects of the problem. (italic added)

For outsiders, zero free region is another angle abundant with numerical improvements but no groundbreaking insights. For percentage people stop at ~40% because there is no need to proceed further, just like we are not interested in computing the googol-th digit of pi although in principle we could.

The groundbreaking results are like Selberg's that goes from zero to 0.01% (actually it is left unspecified, all we know is the percentage is positive), or Zhang's twin prime bound from infinity to 70,000,000. After this leap the pure numerical difference between 0.01%, 40%, 67% or even 100% is not substantial, and that's partly why Selberg did not even bother to compute it. Also RH will not follow from 100%, because in mathematics 100% does not mean all.

On the other hand, it is also wrong to dismiss such results all together. Riemann already know the real part of all zeros are bewteen zero and one, and RH says they equal 1/2. If someone or some LLM proved they are all less than 0.99, well this would be huge, and I'd bet they would easily get a Fields and be remembered forever. Innocent looking results could have drastically different technical depth behind them.

Alas math ppl tend to agree that RH will not be proved one bit at a time. The fundamental arithmetic aspects, once found out, will likely knock out not only RH but all the other L-functions in one go.

> Tesla is faltering so badly in China.

Huh? In June the best selling EV in China is Model Y across all price ranges. Model 3 a tie for the 8th with many ~$10k entry level higher up. If you only rank among ~$40k, then it's a tie for the 4th.

This is very very far from faltering so badly.

If you consider Tesla in China to be Chinese, then BYD in EU would be Hungarian in the parent comment. Japanese brands also manufactures in Mexico, so Mazda is suddenly Mexican now? I've never seen anyone claiming such stuff, except when it comes to anything China.

Model Y remains American just like iPhone, regardless of where they are made. Nobody refers to iPhone as Chinese or Indian.

In the June just passed Tesla Model Y is the best selling EV in China.

Sounds impressive in relative terms but not quite so in absolute terms, because PCB is dirty cheap so 100% is just $10-$20.

Actually it is the opposite, OshPark quality is consistently higher than JLC for years. Chinese manufacturers can do Apple products but also Temu craps, so don't get your hopes high. The only reasonable expectation is being cheap reduces quality.

handle584··on Top researchers leave USA for the Netherlands (in Dutch)
Technically yes, but the ways US and China treat foreigners are at two extremes.

As long as you are invited and keep your mouth shut about ccp, China does not care about papers. One famous example is an athlete, when questioned about nationality after winning an Olympic gold medal for China, publicly claimed that I am Chinese when I am in China, and American when I am in the US.

> paint China as a good alternative.

I don't think OP is doing this, just stating the obvious. The invitation implies $$$ but not naturalization.

> If you want to live in a country, you might want to actually be a citizen of that country. Does that need explaining?

Yeah might, so it is big question depending on the situation, and even bigger once you got more passports or permanent residence. For example people intentionally avoid US permanent residence or citizenship for global taxation.

> Are you seriously suggesting that people can literally just not engage at all with the society they live in?

All the time, especially the US expats in China. They tend to live in nice communities for foreigners in a few tier-1 cities, they go to western style international hospitals and their kids goes to fancy international schools. Basically employers have everything prepared nicely for them, hence the contrast of China between foreigners and citizens.

In terms of racism in China or east Asia as a whole, there is practically no problem for white ppl, small problem for indians, big problem for blacks.

In the reverse direction in the US there are Chinese/Latino spending their lives in their own ethnic community without speaking English at all, it is not that uncommon, just invisible.

> It has nothing to do with loopholes on anything.

Not sure about India but delivery in China has everything to do with loopholes.

No health care and social security for most, and for the few who have the company artificially fake income for tax evasion.

Working conditions are the usual 12~14 hours a day with 2~4 days off a month.

The electric bike they are riding are dangerously over-limits and categorizes as motorcycles, which are actually banned in most big cities. Of the few that allow it, Shanghai for example, you need to pay ~$70k for registration alone.

In the US the situation is better but not free from problems, for example the first job for a lot of the illegal immigrants who can not speak English is package sorting with similar working schedule, but at least it pays good enough.

This actually applies to the US as well. Anytime you need to send $1k+ to a stranger the process is a pain in the ass.

> A lot of banks report every transaction of your checking account to credit bureaus.

So stable coin is my preferred way, and luckily among my circle it is widely accepted. Any amount is instant with a few cents fee at most.
