The people turning child trafficking into a spiritual fantasy are the ones protecting the actual perpetrators. Real victims hunt the humans responsible. The rest just want to feel special.

About 13,000 years ago, a group of hunter-gatherers in a cave near modern Haifa brewed beer for a funeral. It is the oldest alcohol anyone has ever dug up, and the people who made it had not invented farming yet. They were making drink for the dead before they were baking bread for the living.

Stanford archaeologists found the residue in stone grinding bowls in 2018. Scholars have argued about the order for sixty years. Some think humans planted the very first grain to brew beer with it, well before they used it for bread. That cave is now the strongest evidence they have.

Our pull toward it goes back further still. In 2014, scientists rebuilt the alcohol-digesting enzymes of our ape ancestors. They traced a single gene change to about 10 million years ago, one that made our line roughly 40 times better at breaking down ethanol, the alcohol in every drink. It happened right as those ancestors came down from the trees and started eating fruit off the ground, where it sits and turns boozy. We were adapting to alcohol millions of years before we were human.

Once cities showed up, alcohol helped run them. One of the oldest pieces of writing humans have ever found, a clay tablet from the city of Uruk in what is now Iraq, records a worker's ration of beer. The men who built the pyramids were paid in bread and beer, by some accounts several liters a day. The Sumerians wrote a hymn to Ninkasi, their goddess of brewing, around 1800 BCE, and it is also the oldest known beer recipe. Hammurabi's law code set the price of beer and could sentence a cheating tavern keeper to drowning.

So the reason it became normal is not some modern marketing trick. It is older than farming, older than writing, older than the wheel.

Then the present caught up. In 2018 the biggest study ever run on this, covering 195 countries for the Global Burden of Disease project, found the amount of alcohol that does the least harm to your health is zero. The World Health Organization's cancer agency has filed it in the top hazard group since 1988, the same shelf it uses for tobacco and asbestos.

Ten million years of biology built the appetite for it. The data finally caught up, and the number it lands on is zero.

People think AI companies are hiding alien physics.

Meanwhile Claude will happily explain black holes, quantum field theory, relativity, and nukes.

Ask about biology and suddenly it’s Fort Knox.

The only thing frontier models treat like classified information isn’t physics.

It’s biology.

That’s the real tell.

The Green Stones of Tsavo.
=======

Yesterday, at a roadside restaurant near the land of the Man-Eaters of Tsavo, a local man approached me with attractive green stones.

Tsavo is known for tsavorite, the rare green garnet whose value has been rising sharply. He hinted that the stones were tsavorites from a mine where he worked.

But the stones were too large, too glassy, and too good to be true. If they were real tsavorites of that size, they would not be moving casually at a roadside restaurant for KES 200,000.

Before I even reached for my testing tools, we both knew the truth: they were volcanic glass.

I offered him KES 1,000. He accepted.

I bought them partly out of curiosity, and partly because I did not want them ending up in the hands of someone less informed.

The deeper lesson is not about gemstones. It is about systems.

Many people we call honest are honest because they work inside systems that leave little room for dishonesty. The invoice must be approved. The sample must be tested. The material must be certified. The transaction must be recorded. The audit trail must exist.

Remove those systems, and many shining reputations would quickly be exposed to temptation. Loopholes do not only harm victims. They also destroy the people who exploit them.

That is why serious businesses, serious governments, and serious industries cannot run on trust alone. Trust is good. Verification is better. Systems are best.

A stone is not tsavorite because someone says so. It becomes valuable after testing, grading, certification, and traceability.

The same is true of people, institutions, and nations. Where systems are weak, temptation becomes policy. Where systems are strong, even ordinary people can remain reliable.

@UnearthedHQ Isn’t it immensely more likely that these formations are the remains of volcanic activity and the circles are all that is left from ripples of cooling lava? Monstrous, gigantic trees I guess are possible but where are the remains of the rest of the tree?

The Great Dying in Austinmer, Australia.

Gaze upon the boundary line separating these rock layers.

Seems peaceful nowadays? In geological history, not.

Below the line, a world teeming with life; above it, total devastation. In a fleeting geological instant, 95% of Earth's species vanished into nothingness. The largest and most catastrophic mass extinction in history, frozen right before your eyes.

Firstly, Ethiopia is under US sanctions while Vietnam is not. And speaking of former French colonies, Haiti was the first to get independence (1804) and is still one of the poorest countries in the world because of the debt they had to take on to gain independence (it took them until 1947 to fully repay it!). Whereas, New Caledonia is still a French colony and is neither rich nor poor.

"If colonialism were the answer to why Africa is poor..."

This line completely ignores the European powers' (and US) post-colonial control over Africa. Patrice Lumumba, the first democratically elected leader of the DRC, was tortured and killed by Belgium and the US for being a nationalist. His body was dissolved in acid so he wouldn't become a martyr. His legacy is largely unknown even within the continent. Several other such "lessons" were meted out. Google Thomas Sankara (Burkina Faso) and Sylvanus Olympio (Togo).

Once you set the example, you gain obedience. The VietCong, on the other hand, didn't surrender even though 3 million Vietnamese died during the war, and several thousand more continue to die to this day (!) from Agent Orange exposure.

As for former French colonies in Africa, France still controls their currency and holds their central bank reserves in France. As Rothschild purportedly said, "permit me to issue and control the money of a nation, and I care not who makes its laws."

Third, the borders in Africa were drawn in such a way that conflict was inevitable. At the Berlin Conference in 1884-85, the European powers simply carved up the continent by drawing straight line borders. African leaders were conspicuous only by their absence at this historic event which shaped the next century. This is why Cameroon, a French-speaking country, has a minority English-speaking territory, ensuring it remains destabilized. Likewise for West Asia/the Middle East, where the Sykes-Picot legacy lives on.

@magattew conflates formal colonial rule with colonial control. Vietnam managed to fully kick out both France and the US, reunified the North and the South, and kept its sovereignty. All African leaders who attempted the same have been systematically eliminated (see Muammar Gaddafi, Libya's divisive leader, for a recent example), ensuring Africa forever bears the open wounds of its colonial legacy.

But Ms. Wade is right on one thing: Vietnam owes its prosperity to overcoming colonial rule. Maybe Africa can become prosperous if Africans do the same.

The straight red line is a 30% grade. The winding one is 8%. That single number is the whole answer.

Grade is rise over run, and the height of the hill is fixed. You don't get to negotiate how much you climb. The only thing you control is how much horizontal distance you spend doing it. The straight shot crams the entire vertical gain into the shortest possible run, which is what makes it the worst option on the board.

A loaded truck starts losing traction past about 12%. A normal car can't pull away from a stop on much over 20%. Going downhill, brakes on a sustained 30% grade overheat and fade inside a mile, which is the entire reason runaway truck ramps exist. So the straight road saves you nothing. Most vehicles physically cannot drive it.

Switchbacks quadruple the distance to cut the grade by a factor of four. Same elevation, four times the run, a quarter of the steepness. A 30% wall turns into an 8% climb a fully loaded semi can take in low gear and come back down without cooking its brakes.

Then there's cost. A straight road up that face needs deep rock cuts and heavy retaining walls to stop the slope from sliding onto it. The winding road traces the natural contour and moves almost no earth. Cheaper to build, cheaper to drain, far less likely to fail.

The shortest line on a map is almost never the cheapest line in physics. Water worked this out a billion years before engineers did. Rivers don't run straight down mountains either.
