My speculation on this has been that it's potentially a factor against ai psychosis, as psychosis risk (of any psychosis) is significantly elevated with lack of sleep. If you read case studies of ai psychosis, many of them also involve people staying up way too long right before they fall on a bad path.
Having tried GLM-5 and Minimax M2.5, alongside regularly using Opus 4.6 (on default thinking): Opus is still much, much better at writing non-garbage code. I haven't yet tried GLM-5.1 though.
I can assure you that south east asians also still have cards, despite not making most of their payments with it. Not all ATMs support withdrawing with just a QR code from all banks, for one.
There are benefits to non-QR based payment systems, such as not wanting to pull out your phone, open an app, scan a QR and approve to make a payment that takes me 2 seconds with regular contactless payments.
Physical cards are also a nice fallback to have in cases of running out of battery, theft, etc.
We do actually. The German Girocards were, until Maestro ceased to exist, often co-issued as Maestro + Girocard, and global acceptance was pretty good under the Mastercard network.
There are examples of other co-branded national payment systems out there (troy + Discover comes to mind).
If a European payment system (with cards, at a store) is to exist, then visa/mc will still want a piece of the pie by at least playing along to remain as a co-brand and taking their cuts from international payments.
The payment processing rates offered vary by country. It rarely goes above 1% in Germany unless you're really not shopping around or are really low volume.
A % of that also goes to the issuing bank*, not to MC/Visa, so I suspect the mentioned 0.2% is talking about what MC/Visa has as their cut.
*: That's also how banks can profitably offer things like cashback.
The fees for those are still often comparatively lower to the US rates posted above. Credit cards are also not popular here, so while I do own one, I suspect average % of a merchant still remains low.
Amex also offers pretty good rates to low-volume merchants here to have more acceptance to my understanding.
The rates I posted are the full range. Because it varies yes.
You suspect average percentage is low but try to get a payment processor agreement and see within two years what you actually pay overall. It may get even above the rates I mentioned with fix costs the jeopardy to your business when a fraud does occur and the issuer blocks you from accepting any payment, or worse, accuses you of being the fraudster.
We are well educated by the financial system and VISA/Mastercard to believe this technology is for our own good. Many in the financial industry denounces their predatory practice, that of a cartel of 2 or 3 that imposed a dictate for decades. Things are finally changing, resistance will continue but you will see QR or some alternative will settle in.
fwiw: Discover technically goes through amex network in EU, and amex acceptance varies from pretty good (e.g. germany) to pretty awful. Completely incomparable to visa and mc acceptance ofc.
Where I live we have labor rights and if your job is delivering mail and you're given a horse for it, you'd only be expected to deliver as much mail as you can in your contractual work time, which is then limited by the legal limits (8 hours/workday, up to 6 days/week). So you'd be home for most of the day, but delivering less letters per day.
(where I live a car would also be slower for delivering mail than a horse, most delivery people are given trikes, but alas)
This is how all industrialization/automation works in general: When you have a way to deliver faster/more, you're given more mail to deliver in your work time. Your pay does not go up, but any given road blockage or instance of traffic makes you fall behind quota significantly more. You're not paid by how many letters you deliver, but by the hours you work. Maybe you even make less as there's less overtime. Post will then proceed to simply employ less people over time as each employee is made to deliver more letters, then maybe you're part of the people whose jobs are cut. Or they might just reduce wages for everyone anyways, as now the job is much more accessible and there's more supply of labor than there is demand.
This is not an argument against industrialization or automation, but your perspective of what would happen if we had more industrialization is... very narrow.
We must consider the potential future where there's simply not enough work for most people to do (a realistic future now), and how we'll prevent that from going the same way it would currently go (losing income -> losing domicile -> starvation/freezing/etc).
