the key component of ASML is invented and manufactured by the US, that is how the US can force ASML not to export its EUV machine to China. it is an American tech. Airbus is not the result of high tech manufacturing, it is the result of setting up regulations to stop others to join the competition.

I LOL'ed. Saab doesn't have any expertise to build modern aircraft.

People should realize China is huge and manufactures one third of world's goods. You're going to have excellence and crap across such a gargantuan amount of production and companies, a high amount of variance.

High amount variance of quality is a daily reality and as any chinese consumer we are very used to that since the beginning of e-commerce. However there are multiple aspects to the quality feel. Production of high quality items is one thing (e.g one can do better QA etc), what I heard from some local car garages in China is that standardisation in the industry is still quite poor. E.g Parts to replace and bolts and n…

Also the enforcement of standardization is really poor, almost to the point nobody cares.

Chinese manufacturers can make quality stuff and can be rather honest to work with once you show certain knowledge of the field, they will even tell you which products are to avoid.

> The reason most people still believe that Chinese-made stuff is poor quality is because they will do what they are told and they are usually told “make this as cheap as possible” by whoever is paying the bills. I’m reminded of all the dismissals people made about the skill levels of Indian software developers when the explanation was that the more skilled ones knew they could do better than the MBAs were offering t…

Also because of the appalling track record of QA/QC, and subsequent cover-ups, at every level of government and enterprise from regional to national. In the 2008 milk Scandal, for example, the offending company Sanlu were aware of infants becoming sick December 2007, but refused to test until June 2008. Shijiazhuang city governance failed to report the contamination to provincial and state authorities September 2008…

The best part of this scandal is in a press conference a major producer, Mengniu, publicly announced that milk made for Hong Kong is not affected.

This one-sentence message demonstrates a lot of the problems of Chinese manufacturing if you think about it for a minute.

Cars only show if they're well made after like a decade? These are not washing machines or something. Sadly that's also why it's hard to buy a new car, you only know what's a quality car years down the line. First impression matters though.

I’d be stoked if a washing machine lasted a decade.

Look into Speed Queen. They're known for being well-built commercial-grade machines.

I've got a friend whos a master tech/trainer with our state automotive body, and is HV certified etc for dealing with these cars. He's currently got a BYD Shark strewn across his workshop for an autopsy. I have to say I'm super impressed with how heavy duty everything is.

>The control arms, subframes, etc all look good and don't fit the 'chinese car bad' narrative you always hear. While I think the "chinese quality bad" narrative still applies to many Chinese brands, this isn't as universal as it was in the past. I think my eyes were first opened when I bought myself a Huawei phone(before the Google ban). My first few smartphones had been Samsung, I've always felt the term "planned ob…

That's exactly how Chinese android market works, every phone/pad is No.1 upon release and within a few week's PR campaign. After a couple months a new one is released with another No.1 bla-bla, while the old one goes on life-support.

Also have to mention their ads, built into the system, when every app opens, when you switch back, f*king everywhere. The funny thing is if you switch language to English or use it overseas, some of the ads will go away, ironic.

That doesn't mean that China is incapable of producing high quality goods, but just that the average interaction that people have with Chinese goods are low quality. It's the manufacturing equivalent of "How could the government be efficient? H…

While true, imho its more complicated than that * PE, on the whole, has extracted wealth from quality. This is true at both the consumer level and B2B. E.g. its impossible to trust any aftermarket car part manufacturer, and some OEM brands have turned to dogshit too. * "most people just buy trash at WalMart and Amazon" I'd rephrase that to: most people either can't or are unwilling to pay the premium for quality in a…

I'm very willing to pay a premium for quality, I just can't seem to find any reliable signal for quality before buying. Price and brand are both increasingly meaningless signals.

Oh, I love the 2 sides of HN... Here everybody's ready to buy a BYD and even move to China, due to the sheer quality of the product (for the money) and the integrity of the people, totally forgetting about the 'social credit system' and the data that these cars might be sending or being exposed to having the car remotely disabled. Not to mention the repairability... Just a few days ago there was a popular post taking…

I frankly could not give less of a fuck about China spying on me. Spy away. At least they don't communicate their findings with my government. What I do care about is my own government spying on me, or domestic companies spying on me and selling that information to my government.

>I wish China didn't have such a hostile government to the West. In what way are they hostile? I am also part of "the west" and they never threatened us. The west != just the USA.

Are western companies able to freely compete in China? Last I checked, no, they need local partners at best, or are blocked completely at worst. And not just American but any outside company.

Lots of countries are like that though. America has an unusually free system where anyone can do anything for better or worse, but Walmart failed in Germany by ignoring all the local processes like employee protections. (But I hear Aldi is taking over the UK!)

> Vertical integration matters. If BYD controls much of the chain from the mine to the ship, they’re not paying everyone else’s margin along the way. That can translate into more car for the money. This is interesting. Wasn't the idea in Europe (and maybe elsewhere, too, no idea) that outsourcing components would lead to economies of scale? After all, a Mercedes or BMW or VW seat is still roughly a seat? It's interes…

VW, Mercedes and BMW also squeeze their suppliers very hard, and they operate with razor thin margins. So I agree and wouldn't say that doing everything in house is always going to be the cheaper way

The value in being a supplier is you make the replacement parts when they start breaking in 5-10 years. The real money is in selling to every auto parts store in the country.

So in the first 5 years, no reason not to buy it. Basically proving the point I was making

What will you do when you want something different? Used car values are partially a function of their expected remaining lifespan, and if the car isn't trusted to last it is worth less.
