(I edited the timeline to clarify)

2015-2021: Google and Cloudinary develop the technical foundations, work on standardization with the JPEG group and write the reference implementation

2021: Chrome and Firefox introduce experimental support

2022: The Chrome team decides to remove the experimental support, citing lack of interest in the ecosystem

2023: Apple surprises by shipping support in all their products

2024: Firefox says they don't want the attack surface of 100K lines of multithreaded C++ but they will ship support if Google implements a Rust version

September 2025: Google delivers jxl-rs v0.1.0 (a Rust implementation)

October 2025: The PDF Association announces they want to include the format in PDF, citing the need for HDR support in particular

November 2025: The Chrome team reverses its position, citing Safari support, Firefox's new stance, Interop proposals and the PDF announcement.

So while Google played the largest part by far in making JPEG-XL a thing, Apple probably played an outsize role in getting it adopted so fast. But its long-term fate? Who knows... The PDF Association might well have adopted JPEG-XL without Apple: they cited HDR support, wide-gamut, ultra-high resolution and channel number, not "works on iOS". And having it as the format for HDR in PDF would have forced Chrome's hand no matter what Apple did.

(Small heads up: the "anyone with a clue agrees with me" framing is more grating than useful.)

If you mean run different tests, where you collect different kinds of data from the same individual, sure but that's not something you can "just do" in the general case.

Regarding the nuclear threat posed by Iran: the deal Obama made with Iran was not perfect but it was working, at least on that aspect. Quoting the New York Times[1]: "Under the deal, Iran shipped 98 percent of its uranium stockpile out of the country. Iran previously had enough uranium to fashion eight to 10 atomic bombs once fully processed; afterward it was left without enough for even one". It also enabled an unprecedented level of inspections by the IAEA.

Compare that with what Trump has achieved so far... It's really sad that he had to tank that deal because he couldn't stand Obama having a great lasting diplomatic achievement. So Trump effectively manufactured the conditions for Iran to be a nuclear threat again.

I also don't see evidence that Iran wants to target Europe. The Iranian government does have a despicable rhetoric (mostly against Israel) but their actions have been limited. Israel talks less but inflicts far more harm. Iran has indeed been messing around the region and in particular "holding Lebanon hostage" to some extent with the Hezbollah... We'll see if that gets better after this war.

As for holding internet cables hostage and such: they are just playing the only cards they have, as they are being forced to, by the US.

> Besides, you care about 1 thing: that the oil price rose a bit.

I'm personally rather happy that oil prices are rising. We should get off oil as fast as possible for geopolitical and ecological reasons.

> And yes, I'm very sorry how inconvenient it is that the rest of the world does not just let you live in peace.

Not sure what you mean. We had international institutions and international law to try and avoid conflicts. The UN is a beautiful project created by the US at a time when they had good thinking people in charge. Trump hates and tries to dismantle international institutions. He likes the law of the jungle. It puts us all closer to WW3.

The reaction was predictable and very much understandable from a human psychology perspective. So in my mind the responsibility for the strait being closed rests mostly with the US.

> The president is fine, btw. It was the "supreme leader" that got killed

In Iran the supreme leader is the head of state. In the US it's the president.

> he is known to have ordered the extermination of 600,000 Syrian muslims

Do you mean the Syrian civil war? According to Wikipedia it's 650,000 deaths on all sides together (more than half being combatants). I'm not sure it's fair to attribute all these deaths to Iran. By the way these numbers are similar to those of the Iraq War of GWB.

But I guess that was a distraction from the main point: If consciousness emerges from biological processes in the brain connected to the world with a body, why would it not emerge from a simulation of these processes connected to the real world with sensors and actuators?

It seems like circular reasoning to me: The simulation is not like the real thing because it lacks the special thing that enables consciousness (that's Searle's biological naturalism). And it lacks what enables consciousness because it's not the real thing (that's the weather analogy).

I mean this Typst package just lets you import the notebook content in your Typst document. All the formatting is done in Typst which is also what you use for your final output...

Indeed user-defined functions are pure. You can work around it like the suiji package[1] does: have the function return a value that you pass as argument to the next call.
