“I grow old ... I grow old ... I shall wear the bottoms of my trousers rolled.” - T.S. Eliot
Anyone who takes up an instrument in adulthood, late and a little embarrassed about it, learns the same deflating secret in the first month.
The notes are not the hard part. They are right there in the book, and a phone will now play them back at any speed, looped and slowed and fingered, until the passage that once defeated Casals sits demystified in your pocket. What the phone cannot hand you is the tedium of the four hundredth pass through the same eight bars, the dead middle of a Tuesday when nothing improves and no one is in the room and the only argument for staying in the chair is that you have decided to become a person who stays in the chair. The mastery, when it comes, was hiding in that tedium the whole time.
The knowing was free. The sitting with it through hours of boredom and frustration and a whole host of unpleasant feelings was the price.
Money learns the same thing the hard way. In the second week of August 2007, the best-paid mathematicians in the world watched their models stop working at the same minute. They were the quants, the funds that trade by statistics instead of judgment, running long-short books built on small reliable patterns in how prices move, mined from decades of data. The strategies had printed money for years. That week they gave it back in days, ten percent, twenty, some more. The losses came from all of them being right in the same way. They had found the same patterns and were holding the same positions, and when a few began to sell, the regularities they all leaned on bent the wrong way at once, and the selling fed the selling. Amir Khandani and Andrew Lo, two MIT researchers who rebuilt the week from the transaction records, gave it a flat name: a coordinated deleveraging of similarly constructed portfolios. The edge each fund had paid a fortune to discover was the same edge, and shared, it was a fuse.
AI has since made everyone a quant.
A pattern that anyone can find has a short life.
In 2016 two finance scholars, David McLean and Jeffrey Pontiff, took ninety-seven of the published signals that academic papers had shown could predict stock returns, the kind of edge a quant builds a fund on, and measured what happened to each one after its paper appeared in print. The returns fell by more than half. The act of publishing the pattern was the act of killing it, because once it is known it is crowded, and once it is crowded the money that the pattern used to pay is already gone. The edge lived in the scarcity of the people who could find it. That scarcity is now sold by subscription. Any teenager with a chatbot can scrape a dataset and surface a regularity that in 1990 would have funded a yacht, and the regularity is worth, for exactly that reason, nothing.
This already happened to the Torah. In 1994 the journal Statistical Science published a paper by Doron Witztum, Eliyahu Rips, and Yoav Rosenberg claiming the names of rabbis who lived centuries after Moses were encoded in Genesis as equidistant letter sequences, at odds the authors put at one in fifty thousand. Someone had run the script on the Torah and the patterns were there. Then Brendan McKay and his colleagues ran the identical method on War and Peace and pulled the same codes, rabbis and dates and all. The patterns were real everywhere and meant nothing anywhere, which is why the tradition ruled, long before it had a computer to tempt it, that you do not derive a law from a number.
Rabbi Eliezer ben Chisma taught that the dense unglamorous laws of bird-offerings and menstrual reckoning הֵן הֵן גּוּפֵי הֲלָכוֹת, “these are the very body of the law,” while astronomy and gematria, תְּקוּפוֹת וְגִימַטְרִיאוֹת, are פַּרְפְּרָאוֹת לַחָכְמָה, “condiments to wisdom” (Avot 3:18). The patterns are infinite, and a method that finds everything has found nothing. Ben Bag Bag said of the Torah, הֲפֹךְ בָּהּ וַהֲפֹךְ בָּהּ דְּכֹלָּא בָהּ, “turn it and turn it, for everything is in it” (Avot 5:22). The sages assumed an infinity of patterns from the start.
There is a story about the giving of the Torah. Moses climbs to receive it and finds God tying little crowns to the tops of the letters, and is told that generations on a shepherd named Akiva, come to learning late, will expound heaps of laws from each stroke. Set in the back of Akiva’s study hall, Moses cannot follow a word of the lesson spun out of his own Torah (Menachot 29b). The crowns were always there, the readings latent in them.
The old edge was finding what others could not see. The new edge is holding what others cannot bear.
There has always been a second kind of investor at the other end of the room from the quant, who buys a few things he believes he understands and holds them while the market calls him a fool, for years sometimes.
His whole edge is the stretch the professionals call drawdown, and he does not sell. The information is on everyone’s terminal. The pain of holding through negative momentum is his alone, because the holding hurts, and most people will pay almost anything to make the hurting stop.
Warren Buffett put the mechanism in a sentence: the market is a device for transferring money from the active to the patient.
You cannot script patience. It is not a search, and a machine that runs a million searches a second has no advantage in a contest that rewards sitting still while you bleed. The counterfeit is holding only while the position quietly keeps paying, and calling that comfort conviction.
The quants in 2007 held until the signal stopped paying, then moved toward the door at once.
Bachya ibn Pakuda, an eleventh-century sage of Zaragoza, found the same thing named in the oldest place. The book of Job opens with the Satan putting one question to God about his most faithful servant: הַחִנָּם יָרֵא אִיּוֹב אֱלֹהִים, “does Job fear God for nothing?” (Job 1:9). Job has served, Bachya writes, כְּסוֹחֵר, like a merchant, taking the honor of the world as the price of his devotion (Duties of the Heart, Tenth Treatise 4). Strip the payoff and see what stands. A faith that holds only while it is paid is a position someone else is funding.
Judaism is, among the many things it is, a very old technology for holding a position through drawdown.
It has a precise phrase for the worst of it. Hester panim, הֶסְתֵּר פָּנִים, the hiding of the divine face: the long stretches when God withdraws, or seems to, and the world runs on as though no one is home and no prayer is heard.
The Torah names the condition in the voice of God, doubling the verb so the deliberateness cannot be missed, וְאָנֹכִי הַסְתֵּר אַסְתִּיר פָּנַי, “and I will surely hide my face” (Deuteronomy 31:18). The Psalmist holds his position straight into that silence and asks the only question a man underwater has, עַד אָנָה תַּסְתִּיר אֶת פָּנֶיךָ מִמֶּנִּי, “how long will you hide your face from me” (Psalms 13:2).
The founding scene of the entire inheritance is a drawdown trade, named a test in its first verse, וְהָאֱלֹהִים נִסָּה אֶת אַבְרָהָם, “and God tested Abraham” (Genesis 22:1), the ask escalated word by word to its most beloved object, “your son, your only one, the one you love” (Genesis 22:2). Then a mountain three days off, and Abraham goes. The three days are the whole point: a single terrible instant could be survived on adrenaline, but three days is long enough to think, to turn back, to be talked down by every sane part of a mind. בַּיּוֹם הַשְּׁלִישִׁי וַיִּשָּׂא אַבְרָהָם אֶת עֵינָיו וַיַּרְא אֶת הַמָּקוֹם מֵרָחֹק, “on the third day Abraham lifted his eyes and saw the place from afar” (Genesis 22:4). The destination stays in view the entire climb, mei-rachok, at a distance, visible and unreached while the loss compounds. At the foot of the mountain he tells the servants, וְנָשׁוּבָה אֲלֵיכֶם, “and we will return to you” (Genesis 22:5). We. Both of us. He says it walking toward a slaughter he believes commanded, with no evidence for the return except his refusal to close the position. When the knife is stopped, nothing he did not already carry up the mountain is handed back. The voice says only עַתָּה יָדַעְתִּי כִּי יְרֵא אֱלֹהִים אַתָּה, “now I know that you fear God” (Genesis 22:12). The trial pays out in proven character, and in no new information at all.
The text that carries this carries it, at its sharpest, inside a single word the scribes could never resolve. Job, stripped of his children and his health, scraping his sores in the ash, turns on God and says a thing that comes down to us doubled: הֵן יִקְטְלֵנִי לֹא אֲיַחֵל: though he slay me, I will not hope.
The Masoretes, the scribes who fixed how the Bible is read aloud, set against them a different word to be spoken, לוֹ: though he slay me, in him I will hope!
They refused to choose, writing one and reading the other, so the line means, at the same instant, I am finished and I am still here (Job 13:15).
Faith turned out to be the word written as despair and pronounced as trust, and the refusal to collapse the two.
That is the interior of a drawdown held to the end: the position and its ruin pressed so close together that a single syllable carries both.
The quant is in Claude Code, scanning the Beit Midrash right now. I should know; we at Lightning built a knowledge graph plotting 16M relationships between 2M entities in our library of Jewish texts. the study hall, with the machine open beside him. The quant can find every pattern the tradition took two thousand years to notice, every crown on every letter, and also a great many that mean nothing, the codes that also sit in War and Peace.
What is left is the thing Abraham did for three days, and the Masoretes did to a word in Job, and Ben Bag Bag meant in the half of his line no one quotes, וְסִיב וּבְלֵה בָּהּ, grow gray and worn out in it. To stay in the position across the long stretch when nothing rises and the face is hidden and the only evidence the trade was ever good is that you have not closed it. The machine will play every note before he reaches for the first, and read the verse a thousand ways before he reads it once.
It never has to stay in the chair. But you, you must grow old in it.




Having started learning to play the jazz drum kit at an advanced age I totally feel
your position. I would just add one note. Take joy in it, this quiet patience. Don’t criticize or judge while you wait and the world will become much clearer despite being even more incomprehensible.
Magnificent!
