I think we need to put this in context for folks who are not from Brazil.
Comparatively, a domestic bank wire in Brazil before Pix was already easier and faster than one in the US today. I don't recall the bank fees being bad either.
The issue is that bank wires were never designed for buying lunch at the food court. They're not instant and not user friendly to set up.
Pix is alien technology next to the stuff we have in the US.
The entire problem solved by Pix is an artificially created obstacle put in place so banks can charge for something they do for free.
The article doesn't mention China's digital renminbi, but it is similar, including the aspect of being offered by the country's central bank.
Rather than this looking like "Alien tech" in the US, it's just another example of things in the US looking more like stone age tech to the rest of the world.
Like banned chinese EVs, and a pushback on solar electricity generation, all of these are manifestations of the US government primarily making it easier for multi-billion $$ multi-national corpses to filch the general population.
This isn't just the orange cheato, it's been the policy of every modern US administration, with the backing of the majority of the legislature.
And for some reason, the plurality of voters seem to be in favor.
It’s a distributed transaction, which is what makes it complicated. You need to atomically remove money from an account in one database and add money to an account in a totally separate database.
There’s a bunch of weird corner cases that come with that. What if the receiving account ID doesn’t exist, or the recipients bank flags the transaction, or the sender closes their account before the recipients bank has applied their end of the transaction.
I think some of these transfer systems are simpler because they’re global so both records are in the same database. Transactions can be technically atomic rather than organizationally atomic (ie atomicity is present in the technology, rather than approximated by processes).
It sounds a bit like the Dutch Tikkie with the QR codes and instant transfer. Of course, in the EU most bank wires are already free when using SEPA, and often nearly instant as well. This Tikkie thing is a way to easily create a payment request for people who can't be arsed to simply carry cash (and raise the country's resilience to system failure in the process).
Brazilian living in NL, experienced in both. I think biggest difference is Tikkie doesn't give you an easy identifier. Great for privacy, but being able to send money to your email/phone number makes a difference for some real time use cases. QR code helps, but it is not the same.
Since last year, all EU banks have to support SEPA Instant Transfer, both receiving & sending, at the same price as a usual transfer (Instant Payments Regulation 2024/886)
If only https://en.wikipedia.org/wiki/EPC_QR_code supported a sepa instant bit so that one could just show a qr code, scan it with whatever payer banking app and authorize the sepa instant payment.
This is what Ideal/Wero does. Because this is the standard for webshops in the Netherlands (and rapidly expanding to the whole EU) the only gap left to fill was that of consumer-to-consumer transfers with just a QR code to scan. Tikkie I mentioned above solves that well enough in the Netherlands, although that bank-run app is horribly laden with stupid ads and deals you can't seem to turn off.
Pix is ok - but it’s clunky to use and has a single point of failure.
On the former - paying is:
Unlock phone
Launch app
Authenticate
Choose to pay with pix
Scan QR code
Enter amount
Authenticate again
Wait
Payment made
Show cashier your phone
Which is considerably more involved than a contactless payment.
On the single point of failure side of things - I was at an event in Brasilia a month or so back, pix grinds to a crawl, taking 10+ minutes per transaction, and the drinks queues rapidly got out of hand. As nobody accepts cash any more, and because nobody has a card any more, this meant they sold practically no drinks.
So it ain’t bad but tbh passing bits of paper back and forth is still easier.
There's Pix contactless payment. Both Samsung and Google wallet support. Samsung added a few weeks ago. Google added 1 or 2 years ago.
You can actually pay QR Code Pix now with Samsung by just opening the camera too.
Apple refuses to implement Pix on Apple Pay, and regulatory agencies are trying to change that...
Pix integration with Google Pay it's just amazing.
Imagine the situation in the US as if every app or website magically used Google Pay.
Well, that's Brazil now if you use Android. Because as soon as you copy a Pix code, it will prompt Google Pay :) And every service in Brazil have Pix... Even international ones as Stripe supports...
USD is a hard currency unlike the BRL. It is not supposed to move that fast by design. Google “Regulation E”. Brazil has no such strong provisions for protecting unauthorized transfers out of your account
Doesn't seem too different from QRIS in Indonesia, authentication is relatively painless since some apps offer either pin or fingerprint. Being open standard (multiple banks, electronic wallet and payment gateways support it, multiple payment apps support it, all interoperable) probably help since there's never any delay I've experienced for years, and this system is handling from small payment on roadside hawkers to electronic purchase in large stores both offline and online.
More fancy payment flow are also available, such as vendors generating one-time QR code that already include the payment amount, and the user apps generating one-time QR code that the vendor scan, thus switching some of user steps to the vendor.
In most cities I've lived and visited, using QR is far more convenient than paper. Good luck using contactless when most phones don't support it, and even when Visa & MasterCard pushed their contactless standard, I never encounter a single vendor with a working machine (this range from small shops to large hypermarket). Maybe because they have bigger MDR than QR, but from customers PoV contactless simply don't work, until QRIS also adopt NFC and suddenly it's workable (but not widespread yet since most phones still don't)
Speaking as a non-expert, I think Pix has much bigger scope. Pix is account-to-account. One can buy real estate, pay bills, make person-to-person and business-to-business transactions, government payments, recurring payments. The funds also settle instantly.
Most people don't experience the full scope of Pix which is impressive.
Sounds like pix is very similar to the Swedish swish. Phone numbers are used for identity, payments are instant, businesses often have qr codes with their identity etc..
As is the dominant e-ID platform, because our politicians are fond of bank cartels.
It kind of works and Swish does too, unless they're down which happens every now and then, but there is room for improvement that would be easier realised as a public sector endeavour.
The credit card companies really missed the boat here to become the standard for consumer to consumer payments. Of course, from their perspective, they know that people would not accept having to pay for this service so the companies won’t go near it.
My understanding is that FedNow could become something like Pix, but implementation is voluntary. In Brazil, the central bank required all retail banks of significance to implement Pix by a certain deadline.
Visa and Mastercard are very much against FedNow becoming widely used, as it would destroy their business.
The primary goal of this program is not to make a plane, it's to spend $2 trillion in military contracts. As a side effect, it runs as a jobs program for engineers and its US based supply chain. Technology gets developed but with a super low ROI.
xv is my favorite image viewer of all time. I loved how it launched immediately and made it very easy to see an image or browse a folder right from the command-line. 20 years later, computers are dramatically faster and such a fundamental task has become unbearably laggy.
It's the web, it's not supposed to get local files it gets web files and we don't ole for a reason. microsoft tried that with IE(activeX) and found out the hard way. but despite that it does a pretty good job linking and embedding javascript. to the point that they had to invent the whole CORS lunacy just to slow it down.
Elon can't legally financially entangle Tesla to SpaceX due to Tesla being a public company, so his hands are tied.
Tesla is clearly benefiting from protectionism and its sales would collapse if BYD were allowed to openly sell in the US. Most people just want affordable, maintainable and reliable cars.
> Elon can't legally financially entangle Tesla to SpaceX due to Tesla being a public company, so his hands are tied.
He absolutely could do it, just like he did when Tesla bought SolarCity. It just isn’t as easy when one of the companies is public than when both are private.
We're witnessing a bailout and downloading of costs, at scale. Whether or not one buys into whatever the vision of these companies are - it's clear, there's interdealing.
Tesla theoretically now owns a chunk of xAI... whose valuation will no doubt increase due to the internalized SpaceX acquisition. Append to this a future IPO, as discussed in the artice, presumably an eventual premium of 20-50% (reasonable, 14% purely for the ibankers when this will happen)... yields to an interesting bailout situation.
To me, the real question is why. The $2B from Tesla can't possibly move the needle for any party involved in this transaction. If this were to be work 50x as opposed to a potential 50% upside (hell, make it 2x for argument's sake) it still doesn't compute. So what's the actual reason.
> Tesla is clearly benefiting from protectionism and its sales would collapse if BYD were allowed to openly sell in the US
So would most of EU car makers in Europe. China is not playing by the same rules and everyone with car manufacturing domestically is slamming them with tariffs.
How isn't China playing by the same rules? Every country subsidises and supports industry it thinks is important, surely nothing would stop Germany from investing into Volkswagen and BMW or the US from investing into Ford the same way China invests into BYD?
Environmental regulations around rare earth minerals needed for the batteries. China loosens them thus making it cheaper to mine which starves out all global competition that actually has tighter regulations which protect the environment.
Then of course there is cost of living and salary; both of which are lower in China compared to where most legacy auto manufacturers are.
So China can pay their employees less and pollute the environment more in order to create an affordable, very high quality vehicle.
I can understand a small amount of tariffs to help "even the playing field" but not the 100% tariff or whatever was proposed against BYD
Hm, how are tariffs state subsidies? They're a tax on some products to give other products a competitive edge, but that feels different from a subsidy?
And what does that have to do with China playing by different rules than the west?
If not for the tariffs, the domestic company would have to charge lower prices to make sales. Thus tariffs provide domestic companies with additional revenue from domestic consumers.
Tariffs and subsidies both help companies succeed, but they're not the same thing. For one, tariffs can only really help your country's companies be competitive within your country. Subsidies can help your companies be competitive globally.
He's broken pretty much all the other financial rules.... for example, the amount of blatant self-dealing he gets away with is staggering.
As long as the consequences of his actions continue to increase the paper value for investors, regulations don't really have teeth because there aren't damages. So the snowball gets bigger and the process repeats.
> Elon can't legally financially entangle Tesla to SpaceX
Bill Ackman has proposed taking SpaceX public by merging it with his Pershing Square SPARC Holdings, distributing 0.5 Special Purpose Acquisition Rights (SPARs) to Tesla shareholders for each share held. Each SPAR would be exercisable for two shares of SpaceX, aimed at enabling a 100% common stock capitalization without traditional underwriting fees or dilutive warrants.
With SpaceX IPO set to be one of the biggest of all time, this could have a pretty gnarly financial engineering impact on both companies -- especially if the short interest (direct or through derivatives) remains large.
Why would SpaceX go public? They already have a robust enough private market to give liquidity to all of their employees and shareholders who want it. They can get more private investment.
Going public would add a lot of hassle for little to no gain (and probably a negative of having to reveal their finances).
It has been widely reported for weeks that SpaceX is planning to go public in a few months. The reason is they have big plans to run a vast network of AI servers in orbit and will need to raise a massive amount of funding. xAI merger fits with that plan. I'd assume SpaceX still plans to go public.
Was ignored on HN but here's an article explaining:
It's all BS. There is no viable way to put industrial levels of compute into a space based platform that can work within the severe thermal, power, mass/volume, radiation, reliability, and economic demands. It is just stupid smoke blowing to separate idiot investors from their money. J-school grads don't have a clue what they're parroting about.
it wasn't ignored on HN, there were many articles correctly noting that building data centers in space is a stupid stupid idea because cooling things there is infeasible
Google, Blue Origin and at least 5 other smaller companies have announced plans to build data centers in space. My understanding is the cooling issue is not the show stopper you assume.
yup, bezos said "we will be able to beat the cost of terrestrial data centers in space in the next couple of decades". presumably this means they'll need huge ass radiators, so its all about bringing down launch costs since they'll need to increase mass.
Was doing some back of the envelope math with chatGPT so take it with a grain of salt, but it sounds like in ideal conditions a radiator of 1m square could dissipate 300w. If this is the case, then it seems like you could approach a viable solution if putting stuff in space was free. What i can't figure out is how the cost of launch makes sense and what the benefit over building it on the ground could be
AI datacenters are bottlenecked by power, bandwidth, cooling, and maintenance. Ok sure maybe the Sun provides ample power, but if you are in LEO, you still have to deal with Earth's shadow, which means batteries, which means weight. Bandwidth you have via starlink, fine. But cooling in space is not trivial. And maintenance is out, unless they are also planning some kooky docking astromech satellite repair robot ecosystem.
Maybe the Olney's lesions are starting to take their toll.
The shadow thing can be solved by using a sun-synchronous orbit. See for example the TRACE solar observation satellite, which used a dawn/dusk orbit to maintain a constant view of the sun.
Every telco satellite can cool its electronics. However, more than a few kW is difficult. The ISS has around 100kW and is huge and in a shadow half the time.
The cooling is the bit where I'm lost on, but it will be interesting to see what they pull off. It feels like everyone forgets Elon hires very smart people to work on these problems, it's not all figured out by Elon Musk solely.
Google, Blue Origin and a bunch of other companies have announced plans for data centers in space. I don't think cooling is the showstopper some assume.
Good call out, and really interesting. SpaceX being the cheapest way to get things into space, it seems like SpaceX is about to become extremely lucrative.
I've been thinking about this recently as I hear it often. Would people who want to buy a car in the Tesla price range really choose a slightly cheaper Chinese EV if those were available?
Personally I have a hard time believing this. But even if you had similarly priced Chinese options, I would guess the main reason for buying a Tesla is not just because you want an EV. While a Tesla will be a reliable baseline EV, surely the reason you (or at least I) would buy one is for the supervised self-driving feature.
Chinese EVs self-drive too. You can buy level 3 cars today that are cheaper, have more features, better build quality, and better reliability. Having just been in China.. yeah it’s not close they are way ahead of us and the gap is growing fast.
BYD are just affordable and maybe reliable, regarding maintenance their spares are hard to come by and are almost as hard to work with as Tesla and other brands.
I've done plenty of work on my own Tesla. It's not hard to work on at all. Parts are not even very difficult. There are plenty of 3rd party shops (such as one I went to when I needed to replace my windshield.) I really wonder why people continue to think this. It's not 2016 any more.
Tesla body work is extremely expensive. Aluminum, extensive welding instead of fasteners, substantially reduced modularity due to castings, specialized tooling just off the top of my mind.
Body work is expensive no matter what car you're working on. The presence of paint ensures it. The OP was talking about "maintenance" and body work doesn't fall under that category.
No, but I live in a country were Chinese cars have been sold since the 2010s and spare parts are still an issue. It might be an issue with their sales partners here, but many sell other brands from Korea and Japan and have no issues with them.
It's "ironic?" considering Tesla launching in China is what created the necessary supply chain to turn BYD into the powerhouse it is today. Tesla's greed will become their own demise.
Tesla cars made in Shanghai are sold in Europe and other places. That is helping them be competitive and they haven't had much price pressure until recently. Just because the Chinese have their own internal competition and deflation which drove their prices down aggressively doesn't mean it was a bad idea to build there. Also the idea the Chinese couldn't figure it out without an American company coming there first to show them is pretty silly.
Tesla Shanghai opened in 2019
BYD made their first hybrid in 2008 and they were a battery company since the 90s
The only rational reason I could come up with is that the pool of potential Cybertruck buyers is not as saturated as for S/X, which have been around for quite a while.
The Trump administration has gone so far down the path of fascism and crime that I'm convinced they don't simply want to be in power indefinitely -- they need it. Otherwise, the moment a law-abiding president gets elected, there will be criminal charges against all involved. And there's no statute of limitations for murder.
I believe this country will need massive investigations and criminal trials to heal. I am concerned with what happens in between, but this is reality as I see it.
No chance in hell Democrats do a single thing to these people when they're out of power. If anything it'll be a Democrat justifying more ICE shootings so as "not to look weak on immigration"
> I believe this country will need massive investigations and criminal trials to heal. I am concerned with what happens in between, but this is reality as I see it.
Trump learned his lesson and pardoned every Jan 6 terrorist. If he leaves office, he is going to pardon every single person in his administration for anything they did from 2025-2029. There will be no investigations and no criminal trials. They all know this to be true.
Unfortunately liberals seem to care far more about "unity" than justice in any sense. They have been letting conservatives get away with damaging our country repeatedly throughout the decades and always welcome them back with open bipartisan arms. Maybe we could have nipped this in the bud if the confederate states were forced to de-radicalize like Germany was. Instead literal traitors to our country were right back to running for national office again and have been sowing dissent literally ever since. How many Democrats just voted for even more ICE funding for fucks sake?
There were investigations. There were indictments (including four of Trump himself). Here we are. What we learned is that the only constitutional remedy is impeachment (which was also tried twice). What has disabled all the checks and balances is the knife-edge Congressional majority, the takeover of the judiciary, and the purging of the civil service. Changing the President stops the active craziness but doesn't address the underlying problem.
I should have put it differently. I'm afraid that maximum what will be realistically done will be similar to the situation after the Biden got elected. And that didn't help.
> I always thought it was hilarious that a company called Danger lost everybody's data. The connection to Microsoft only makes it better.
Cursed marketing.
Besides the fact that we didn't have any real money to promote phones at T-Mobile (and I think we were the only US carrier with the hiptop) -
Would you believe that the first hiptop came out the same week as 9/11?!
So it was this phone that was arguably two-ish years ahead of the iPhone, but nobody seemed to know it existed, until it got some traction via sheer word of mouth. Everyone who used the HipTop basically wouldn't go back to anything else at all. The HipTop had that 'addictive' quality that the iPhone had. It was nothing like the Blackberry, where people largely used it for a single killer app.
Good point. During that era, a lot of the legacy devices like the famous Nokia brick, the dev work on those was done with actual physical devices.
The smartphone stuff, a lot of that development was running in emulators, which likely reduced the time-to-market.
I distinctly remember seeing devs working on future phones in emulators, but most of the devices we sold were just upgrades to existing devices.
That was probably the moment when Nokia and Ericsson and RIM should have been paying attention to what was happening just south of Microsoft in Bellevue. But none of those three companies had a significant presence in the area at the time, AFAIK. The Silicon Valley folks were flying in every single day. I'd argue that this is what killed Sprint too; they were five hours from anyone. The predecessor of AT&T Wireless was so close to T-Mobile, you could drive from one HQ to the other in under fifteen minutes and you could stop off at Microsoft on the way over.
Definitely an example of the synergies that are possible when you have a couple of tech titans who are less than 90 minutes away from each other via Southwest Airlines.
My impression is that Chinese consumer products haven't been hijacked by the "design above everything else" mindset. The priority is to make things work at scale.
American product design is obsessed with appearance and finish. Products end up costing 3 times more and functionality is degraded.
For real? Every car has looked the same for past 10-15 years. Crossover SUV no matter the brand or big ass truck with flat front. Not to mention the monstrosity that is the Cybertruck that should never have been allowed on the road.
