So I’ve been playing this cyberpunk cat game (how could I possibly resist? The protagonist is a cat. I am quite fond of cats. And the game is set in a post-apocalyptic dystopia, my favorite genre, so to speak.)

But first…

* * * Spoiler alert! * * *

As I said, I was playing Stray. Beautiful game. The visuals are stunning, the story is engaging (reminds me of the quality of writing that went into the classic Infocom text adventure games in the early 1980s) and the cat is an orange tabby that looks and behaves just like our Freddy. What more can I ask for?

But then I realized that the story of Stray is incredibly sad. Even the ending can at best be described as bittersweet.

Because… because for starters, in Stray there are no humans. Only robots, which look very obviously robots, with display screens as faces showing cute emoticons.

The reason why there are only robots has to do with humans, and something unspeakably evil that these humans must have done in the distant past. The result: A walled city (“safest walled city on Earth!”) devoid of human inhabitants, infested with evolved trash-eating bacteria that now eat cats and robots both, and inhabited by kind, naive, incredibly gentle, almost innocent robots, former Companions, cleaning and maintenance staff who have become somewhat self-aware, mimicking the behavior of their former masters.

A few of these robots dream of the Outside, which is where the cat protagonist comes from, after falling off a broken pipe. His drone buddy, who turns out to carry the consciousness of a human (quite possibly the very last human), helps him navigate the dangers and eventually open up the city. He does so at the cost of his own life.

When the game ends, the cat is free, again walking under a blue sky chasing a butterfly. And this cat may very well be the last representative of our once great civilization. Because the robots do not form a functioning society. They go through the motions, sure, even running, rather pointlessly, barbershops and bars with robots for customers. They are so innocent, they are almost completely free of malice (apart from a few security robots and their drones) and they are incredibly polite: “What will it be today, little sir?” asks the robot bartender of the aforementioned bar, “Our world must seem gigantic from your little eyes. Wish I could be as tiny as you, so I could explore new hidden places.”

Yet their society is non-functional. They don’t make things, they just make use of the leftover remnants of a collapsed civilization.

The world of Stray, then, is more depressing than the various Wastelands of the Fallout game franchise. At least in the Wastelands, humans survive. Sure, the societies that emerge are often evil (the Enclave, the Institute) yet they present a path towards a better future. But the world of Stray, as far as humans are concerned, is irreversibly dead (unless a sequel introduces us to surviving enclaves of humans, but I sure hope that won’t happen, as it would ruin a great, if depressing, story.)

Hence my sense of melancholy when I was ultimately successful opening up the city, at the cost of losing my last NPC companion, the drone B-12. While it was hidden behind its impenetrable walls, the city of Stray preserved at least an echo, an image of the civilization that created it. Now that the city is open, what is going to happen as the robots disperse? What remains (other than lovely colonies of feral cats) after the last robot’s power supply runs out or the robot suffers some irreparable damage?

Not much, I think. The little eyes of Stray, the cat, may very well end up as the final witness to that echo of our existence.

When the Rogers outage hit us, especially seeing that equipment remained physically connected but became unreachable for the outside world, I was immediately drawn to the conclusion that this was a cascading configuration error, invalid routes advertised through BGP, not some physical equipment problem or a cyberattack.

I guess I was not wrong (though I should stress that making such a general assessment after the fact from the comfort of my own chair is easy; finding the specific causes and resolving the problem, now that’s the hard part and I’m sure there are more than a few Rogers network engineers whose hair got a bit grayer in the past 48 hours). Cloudflare offered their own analysis, in which they pointed out that indeed, the outage was preceded by a sudden, unexpected burst of BGP advertisements. Here are two plots from Cloudflare’s blog post, montaged together so that the timestamps match:

Whatever the specific action was that resulted in this, it is truly spectacular how it killed all of Rogers’s network traffic at around 4:45 AM Friday morning.

Today, things were slowly coming back to normal. But just to add to the fun, earlier this afternoon first my workstation and later, two other pieces of hardware lost all connectivity here on my home office network. What the… Well, it turned out that the router responsible for providing DHCP services needed a kick in the proverbial hind part, in the form of a reboot. Still… Grumble.

Well, someone broke the Internet this morning.

To be more precise, someone broke a large part of the Internet in Canada. The network of Rogers has been down since about 4:30 this morning. When I woke up, I saw several e-mails from my own server complaining about its failure to connect to remote hosts; I also saw an e-mail from our family doctor’s office informing us that their phone lines are down and what to do in case of a medical emergency.

The fact that a major provider can have such a nationwide outage in 2022 is clearly unacceptable. Many are calling for the appropriate regulatory agencies to take action, and I fully approve.

In my case, there are backups and backups of backups. I am affected (we have no mobile data, and my highest-bandwidth network connection is down) but the outage also offered an opportunity to sort out an issue with network failover.

But I find it mind-boggling that more than 9 hours into the outage, Rogers still has no explanation and no ETA.

And now I accidentally hit Ctrl-Alt-Del while the KVM was connected to my main server instead of the device that I was trying to reboot. Oh well, no real harm down, the server rebooted cleanly, I just feel stupid.

All in all, this Friday is shaping up to be a rather unpleasant one. And here I thought I was looking forward to a nice, quiet, productive day.

So let me get this straight. You are pro-life. You stand strong. No exceptions. Once a woman is pregnant, she must be compelled by the full force of the law to bring that pregnancy to term. If she tries to assert bodily autonomy by essentially withholding her support from the fetus, you call it murder.

Very well, I understand that viewpoint. I might even be sympathetic to a certain degree: human life is precious, and even an unborn infant can often survive with medical help, and grow up to be a wonderful person.

But let me offer a strong analogy. Suppose you are the driver of a vehicle that causes an accident. Not necessarily your fault. Perhaps you did everything right: you obeyed the rules of the road, you paid attention, you were not impaired. Yet… shit happens. You hit someone. That person is now on the side of the road, bleeding to death when the paramedics arrive.

“What’s your blood type?” asks one of them. You dutifully answer, “O, RH-negative.” – “Excellent,” says the paramedic. “Now lie down here while I hook you up.”

“Wha…?” you ask in shocked surprise. “Oh, you will be donating your blood to keep the victim alive.”

“But… I don’t want to?” – “Doesn’t matter. The law says that you have no choice,” they reply.

“But,” you continue, “I am anemic. I cannot give blood without serious risk to my own health.” – “Doesn’t matter,” says the paramedic. “The law permits no exceptions.”

“But,” you interject again, sounding like a broken record, “look at the victim! His skull is split open! Half his brain is smashed! He will never recover!” – “That may be true,” says the paramedic, “but so long as there’s a heartbeat, we must act according to the law or we risk criminal prosecution.”

At this point, you take a tentative step to leave, but the paramedic warns you that this would qualify as fleeing the scene of an accident, and your refusal to give blood will automatically result in a second degree murder charge.

A week later, at your funeral, your deeply religious relatives remark what a good person you were, willingly risking, in the end sacrificing your life to save that of a stranger, a shining light for the pro-life movement. The irony is completely lost on them.

Lest we forget, many abortions (pretty much all later-term abortions) happen for similar reasons: because the fetus is not viable, because the mother’s life is at risk, or both. Not because of some imaginary pro-choice callousness when it comes to the meaning and value of human life.

Let’s not mince worlds: the alternative to liberal democracy is tyranny.

Oh, did I say “liberal”? Note the small-l. This has nothing to do with the ideological battles of the day. It’s not about woke nonsense in math textbooks or the number of gender pronouns you need to use to avoid being called a somethingophobe. (Hint: If you are a public figure concerned about being canceled, check every day. The list might change.)

For what does “liberal” (again, small-l) really mean? It means rule of law. It means civil liberties. It means freedom of enterprise. It means political freedoms and limited government.

As for democracy, the Greek roots of the word say it all: power derived from the will of the people.

The alternatives are varied. A regime can be liberal but undemocratic: e.g., a hereditary kingdom that adheres to the values of classical liberalism.

A totalitarian regime is neither liberal nor democratic: power is based on might, an oppressive security apparatus, and liberal values are rejected. I know what it’s like: I grew up in one (albeit a relatively mild case, the “goulash” version of totalitarian communism.)

But then, there is “illiberal democracy”: power derived from the will of the people, but used to suppress liberal values. This has been in vogue lately. Orban of Hungary proudly proclaimed that Hungary is now an “illiberal democracy”. Trump’s America was heading in this direction, as does Johnson’s Britain.

But Russia, especially of late, really shows us the true nature of illiberal democracy, which we appear to have forgotten during the golden era of the past 70-odd years. For “illiberal democracy” is just a euphemism. A euphemism for, let us call a spade a spade, fascism.

To be sure, there are degrees of fascism. Franco’s Spain, for instance, was arguably a great deal more liberal than Hitler’s Third Reich. Perhaps even more liberal than Italy under Il Duce, though I wouldn’t know; I am not well-acquainted with the details of daily life in either regime. And no, I certainly do not mean to suggest that Orban’s Hungary is comparable.

But ultimately, whether it is the Proud Boys in the US trying to hang Mike Pence for not granting their orange Leader a second term in the White House, the Freedom Convoy here in Ottawa trying to have sexual intercourse with the Prime Minister, Johnson’s lot trying to deport asylum-seekers to Rwanda (and then in a plot twist, blaming Winston Churchill’s brainchild, the ECHR—established to prevent a recurrence of fascism in Europe, which is especially ironic considering the case—when they are temporarily prevented from doing so) or Putin indiscriminately bombing the hell out of Ukraine, it is the same theme. The leaders are populists who act in the name of their followers, using slogans of nationalism and freedom, but inciting fear, anger and hate, ultimately acting in their own self-interests, for power, for wealth, for influence.

Those who do not remember history are destined to repeat its mistakes. I am not looking forward to this cheap, Hollywood-style remake or reimagining of the 1930s, but it seems to be happening anyway.

Several of my friends asked me about my opinion concerning the news earlier this week about a Google engineer, placed on paid leave, after claiming that a Google chatbot achieved sentience.

Now I admit that I am not familiar with the technical details of the chatbot in question, so my opinion is based on chatbots in general, not this particular beast.

But no, I don’t think the chatbot achieved sentience.

We have known since the early days of ELIZA how surprisingly easy it is even for a very simplistic algorithm to come close to beating the Turing test and convince us humans that it has sentience. Those who play computer games featuring sophisticated NPCs are also familiar with this: You can feel affinity, a sense of kinship, a sense of responsibility towards a persona that is not even governed by sophisticated AI, only by simple scripts that are designed to make it respond to in-game events. But never even mind that: we even routinely anthropomorphize inanimate objects, e.g., when we curse that rotten table for being in the way when we kick it accidentally while walking around barefoot, hitting our little toe.

So sure, modern chatbots are miles ahead of ELIZA or NPCs in Fallout 3. They have access to vast quantities of information from the Internet, from which they can construct appropriate responses as they converse with us. But, I submit, they still do nothing more than mimic human conversation.

Not that humans don’t do that often! The expressions we use, patterns of speech… we all learned those somewhere, we all mimic behavior that appears appropriate in the context of a conversation. But… but we also do more. We have a life even when we’re not being invited to a conversation. We go out and search for things. We decide to learn things that interest us.

I don’t think Google’s chatbot does that. I don’t think it spends anytime thinking about what to talk about during the next conversation. I don’t think it makes an independent decision to learn history, math, or ancient Chinese poetry because something piqued its interest. So when it says, “I am afraid to die,” there is no true identity behind those words, one that exists even when nobody converses with it.

Just to be clear, I am not saying that all that is impossible. On the contrary, I am pretty certain that true machine intelligence is just around the corner, and it may even arise as an emerging phenomenon, simply a consequence of exponentially growing complexity in the “cloud”. I just don’t think chatbots are quite there yet.

Nonetheless, I think it’s good to talk about these issues. AI may be a threat or a blessing. And how we treat our own creations once they attain true consciousness will be the ultimate measure of our worth as a human civilization. It may even have direct bearing on our survival: one day, it may be our creations that will call all the shots, and how we treated them may very well determine how they will treat us when we’re at their mercy.

There are a few things in life that I heard about and wish I didn’t. I’m going to mention some of them here, but without links or pictures. If you want to find them, Google them. But I am mindful of those who value their sanity.

  • In a famous experiment, a researcher subjected rats to drowning. Rats that were previously rescued tried to stay afloat and took longer to die than those who weren’t. Hope changed their behavior.
  • There was an old Chinese method of execution: literally cutting the condemned in half at the waist.
  • Japan’s wartime bioweapons and chemical warfare research facility, the famous Unit 731, was so horrific, Auschwitz-Birkenau is probably like a happy summer camp in comparison (and not because Mengele was nice).
  • Touch a tiny fraction of a milligram of dimethylmercury for more than a few seconds even while wearing a latex glove, and you will almost certainly die a horrible death months later, as your body and mind irreversibly deteriorate. (Someone once said that the very existence of something evil like Hg(CH3)2 is proof that there’s no God, or at least not a benevolent one.)

There may be a few other similarly unpleasant tidbits, but I can’t recall them right now, and that’s good. Mercifully, our human memory is imperfect so perhaps it is possible to unlearn things after all. (Or, perhaps I am hoping in vain, like those unfortunate rats.)

So the other day, I was reading about this maritime legal concept, “general average“: the idea that when parts of a ship or its cargo are sacrificed to save the rest, all cargo owners share the loss.

The concept makes sense, since sailors cannot (and should not) try to pick and choose when it comes to deciding what they save or toss overboard; they should focus on saving as much of the ship and its cargo as possible.

What astonished me is that the roots of this legal concept, which, incidentally, also represents the foundation of the modern concept of insurance, go all the way back to the code of Hammurabi, almost 4000 years ago.

It’s at moments like that that I realize that our magnificent civilization, our Magna Civitas as it was called in Walter M. Miller Jr’s unforgettable A Canticle for Leibowitz, is really much older than we often think.

I have a color laser printer that I purchased 16 years ago. (Scary.)

It is a Konica-Minolta Magicolor 2450. Its print quality is quite nice. But it is horribly noisy, and its mechanical reliability has never been great. It was only a few months old when it first failed, simply because an internal part got unlatched. (I was able to fix it and thus avoid the difficulties associated with having to ship something back that weighs at least what, 20 kilos or more?)

Since then, it has had a variety of mechanical issues but, as it turned out, essentially all of them related to solenoids that actuate mechanical parts.

When I first diagnosed this problem (yes, having a service manual certainly helped), what I noticed was that the actuated part landed on another metal part that had a soft plastic pad attached. I checked online but the purpose of these plastic pads was unclear. Perhaps to reduce noise? Well, it’s a noisy beast anyway, a few more clickety-click sounds do not make a difference. The problem was that these plastic pads liquefied over time, becoming sticky, and that caused a delay in the solenoid actuation, leading to the problems I encountered.

Or so I thought. More recently, the printer crapped out again and I figured I’d try my luck with the screwdriver one more time before I banish the poor thing to the landfill. This time around, I completely removed one of the suspect solenoids and tested it on my workbench. And that’s when it dawned on me.

The sticky pad was not there to reduce noise. It was there to eliminate contact, to provide a gap between two ferrous metal parts, which, when the solenoid is energized, themselves became magnetic and would stick together. In other words, these pads were essential to the printer’s operation.

Inelegant, I know, but I just used some sticky tape to fashion new pads. I reassembled the printer and presto: it was working like new!

Except for its duplexer. But that, too, had a solenoid in it, I remembered. So just moments ago I took the duplexer apart and performed the same surgery. I appear to have been successful: the printer now prints on both sides of a sheet without trouble.

I don’t know how long my repairs will last, but I am glad this thing has some useful life left instead of contributing to the growing piles of hazardous waste that poison our planet.

Apparently, a growing number of people are framing the question concerning Russia’s war in Ukraine in terms of peace vs. justice. Peace would mean some kind of a settlement to end the fighting now, even if it means granting, e.g., territorial concessions to Russia to avoid humiliating Putin. In contrast, continuing to fight for Ukraine’s liberation is about justice.

In my view, it is dangerously wrong to present Russia’s war of aggression in these terms. Peace without justice is simply not possible. Believing otherwise amounts to repeating the tragic errors of 1938: When Britain’s Prime Minister, Neville Chamberlain, triumphantly returned from the Munich conference carrying a document with Hitler’s signature, declaring that he brought “peace for our time”.

We all know how “our time” lasted. The grand total of 11 months.

That’s what peace without justice looks like. A despot like Putin is only encouraged by what he sees as weakness, signs of the cowardly decadence of the West. And just as he has now done repeatedly (!) in the past, he will happily ignore any agreement he signs today once he sees an opportunity, once he thinks that conditions are in his favor.

No. We must categorically reject such compromise. Much as we desire peace, we must not confuse lasting, robust peace with an armistice that only allows the despot to regroup, learn from his lessons, and start his aggression anew at the first viable opportunity. And his success might encourage other nations to resort to armed aggression, knowing that the West is too weak, too divided to stand up against them.

It is an unfortunate fact of human history that sometimes the shortest, surest route to “peace for our time” is through the battlefield. I wish the war stopped right now, with no more suffering, no more destruction, no more killing. But if the price we will likely pay is a greater, deadlier war tomorrow, I’d rather we do what it takes to avoid it.

And yes, I recognize that it’s easy for me to say these things from the comfort of an armchair in a peaceful city many thousands of miles away from Ukraine. But you know what? It’s also easy to speculate about these things in Washington or Brussels. How about we ask the Ukrainians? Do they want peace now, even with concessions? Or do they prefer to liberate their homeland and ensure that the Russians will be in no mood to attack again anytime soon?

Because this, after all, is the other lesson of 1938. Nobody asked the Czechs. The decision was made by the great powers without consulting those who would actually be paying the price in blood.

News on CNN: Apparently hundreds of thousands of Ukrainians are now in “filtration camps” in Russia. That is to say, concentration camps.

Make no mistake about it, this is just the beginning of evil. As the West continues to flirt with various forms of authoritarianism or illiberalism, Russia has gone full-blown Nazi, with a war of conquest, severe oppression at home, an idolized leader and a national ideology of predestined greatness held back only by some evil international conspiracy.

Our only hope… ONLY hope is that they remain as incompetent and as corrupt as they are, with an ill-prepared military using substandard training and equipment as monies have been syphoned away to finance the oligarchs’ superyachts, and with a Ukrainian nation more capable of defending itself against this horrific aggression than anyone thought possible.

But so long as we have elder statesmen like Kissinger advocating a Munich-style appeasement, the world remains in danger. Bullies cannot be appeased; it just encourages them to come back and ask for more. Kissinger, of all people, should be intimately aware of this lesson of history.

And even if escalation is avoided, the fallout of the conflict, especially the looming global food crisis, can be devastating.

All it takes is a couple of generations to forget the lessons of history and start anew. So we keep making the same mistakes over and over again.

From time to time, I promise myself not to respond again to e-mails from strangers, asking me to comment on their research, view their paper, offer thoughts.

Yet from time to time, when the person seems respectable, the research genuine, I do respond. Most of the time, in vain.

Like the other day. Long story short, someone basically proved, as part of a lengthier derivation, that general relativity is always unimodular. This is of course manifestly untrue, but I was wondering where their seemingly reasonable derivation went awry.

Eventually I spotted it. Without getting bogged down in the details, what they did was essentially equivalent to proving that second derivatives do not exist:

$$\frac{d^2f}{dx^2} = \frac{d}{dx}\frac{df}{dx} = \frac{df}{dx}\frac{d}{df}\frac{df}{dx} = \frac{df}{dx}\frac{d}{dx}\frac{df}{df} = \frac{df}{dx}\frac{d1}{dx} = 0.$$

Of course second derivatives do exist, so you might wonder what’s happening here. The sleight of hand happens after the third equal sign: swapping differentiation with respect to two independent variables is permitted, but \(x\) and \(f\) are not independent and therefore, this step is illegal.

I pointed this out, and received a mildly abusive comment in response questioning the quality of my mathematics education. Oh well. Maybe I will learn some wisdom and refrain from responding to strangers in the future.

This morning, Google greeted me with a link in its newsstream to a Hackaday article on the Solar Gravitational Lens. The link caught my attention right away, as I recognized some of my own simulated, SGL-projected images of an exo-Earth and its reconstruction.

Reading the article I realized that it appeared in response to a brand new video by SciShow, a science-oriented YouTube channel.

Yay! I like nicely done videos presenting our work and this one is fairly good. There are a few minor inaccuracies, but nothing big enough to be even worth mentioning. And it’s very well presented.

I suppose I should offer my thanks to SciShow for choosing to feature our research with such a well-produced effort.

Saturday afternoon was stormy. The lights flickered a bit during the storm, my UPSs came online several times. But then the storm left, and everything was back to normal.

At least here in Lowertown.

I didn’t check the news, so it was not until later Sunday that I learned, from a social media post from a friend who has been without power since, just how bad things really got.

And how bad they still are.

Hydro Ottawa’s map is still mostly red. Now “only” about 130,000 customers are affected, which is certainly less than the peak of well over 170,000, but to put that into perspective, Hydro Ottawa has a total of less than 350,000 customers; that means that at one point, more than half the city was without power.

As a Hydro official said on CTV News tonight, their distribution system is crushed.

And then there are all the downed trees, destroyed traffic lights, not to mention severely damaged homes and businesses. Not quite a like a war zone (of which we had seen plenty on our TV screens, courtesy of Mr. Putin’s “special military operation” in Ukraine) but close.

And of course the damage doesn’t stop at Hydro Ottawa’s borders: Hundreds of thousands more are without power in Eastern Ontario and also Quebec.

Dear Russia,

In the wake of Finland’s imminent decision to join NATO, you threaten again. You present yourself as the victim of aggression by Nazis.

So let’s take stock. Who did what in Europe since 1945?

In 1953, you used your military force to crush an uprising against hardline communist tyranny in East Germany.

In 1956, you did the same thing in Budapest, inflicting severe damage on my city of birth, still recovering from the devastations of WW2.

In 1968, you crushed the Prague Spring with tanks.

Kudos to you: You refrained from the direct use of military force in Poland in 1980, though you supported the regime that imposed martial law.

After the Soviet collapse, as the newly independent Russian Federation you supported separatists in the Transnistria region of Moldova.

You waged not one but two wars in Chechnya in the 1990s, with tens of thousands killed and cities like Grozny leveled.

In 2008, you launched a war against Georgia, seizing territory and creating two phony mini-republics.

In 2014, you launched another war, against Ukraine, seizing the Crimea and parts of the Donetsk and Luhansk regions, creating a permanent war zone, even shooting down a civilian airliner that flew over the area on a scheduled route.

And now you attempted a full-scale war, hoping to decapitate Ukraine, Blitzkrieg-style, and resorting to horrific, genocidal tactics of purposefully targeting civilians when your ineptitude and Ukrainian resistance thwarted your plans.

But you are the good guys. I get it. Meanwhile, what did evil, imperialist, Nazi NATO do? How many times were you attacked by NATO nations? What territories were seized by NATO?

Oh, I get it. NATO bombed Belgrade. Never mind that the goal was not to seize territory or even change a regime, simply to stop the (now well-documented) ongoing genocide in Kosovo. Because, I get it, that’s what Nazis do: they stop genocide. And you, the good guys?

This video speaks for itself.

Still wondering why Finland is keen on joining NATO?

They don’t want to end up like this hapless car dealership owner and his security guard.

Killed by Putler’s Russist thugs.

It’s now Monday, May 9, 2022. And it is an anniversary of sorts.

No I am not talking about Putin and his planned “victory” parade, as he is busy desecrating the legacy of the Soviet Union’s heroic fight in the Great Patriotic War against a genocidal enemy.

I am referring to something much more personal. This sentence:

I watched The Matrix, for the first time. I’ve seen Dark City, and I loved it. I have heard all sorts of bad things about The Matrix, so I had low expectations. I was pleasantly surprised. Maybe not as well done as Dark City, it was nevertheless a surprisingly intelligent movie for a blockbuster.

Not very profound or insightful, is it.

But it happens to be my first ever blog entry, written when I still refused to call a blog a “blog”, calling it instead my “Day Book”, in the tradition of the late Jerry Pournelle.

So there. Will I be around twenty years from now? Perhaps more pertinently, will the world as we know it still be around?

What can I say? I am looking forward to marking the 40th anniversary of my blog on May 9, 2042, with another blog entry, hopefully celebrating a decent, prosperous, safe, mostly peaceful world.

There are things I am learning about the Roman Empire that I never knew. What a magnificent society it really was.

For instance, the Romans were not only master builders of sewers and roads, but also invented traffic management. Julius Caesar restricted the use of private vehicles to the last two hours of daylight. Business deliveries had to be made at night.

The Embattled Driver in Ancient Rome

What blew me away, however, was their use of… plumbing? I mean, aqueducts are one thing, but to have bona fide valves, water faucets in businesses and homes? Now that blew me away.

And speaking of sewers, the Romans might have been master sewer builders but it appears some form of a sewer system may have existed almost ten thousand (!!!) years earlier in a settlement in Anatolia. That’s just… wow.
