Harvard needs 8% return every year just to keep the lights on. 5% spending plus 3% inflation. Miss that number and buildings stop, professors leave, research dies.
40% of the operating budget comes from one portfolio. Not tuition. Not grants. One fund.
Jake Xia manages that fund's public markets. He also teaches the math behind it at MIT for free. One of the top five most-watched courses on OpenCourseWare. Millions of views. Almost nobody changed how they invest.
Every year he hands students a blank page. Build a portfolio. No rules. Someone writes 100% Apple. Someone writes rare coins. Confident picks. Same blind spot, every time.
Not one student asks the only question that matters: how much goes in each position. They all pick what to buy. Nobody sizes it.
Sizing is the entire job. The answer won the Nobel Prize. It's called the efficient frontier. Xia draws it on the board in under a minute.
Five equations sit underneath it. Compound growth. Present value. The geometric mean. The Rule of 72. Real return. All older than any bank on earth. All fit on a napkin. None behind a paywall.
A "guaranteed 5% bond" during 4% inflation is a 1% return. The industry doesn't hide this. It just hopes you never run the equation yourself.
The lecture is free. The napkin is free. The only thing that costs anything is not knowing.
Je suis tombé sur ce truc ce matin et j'ai explosé de rire tout seul devant mon écran.
Quelqu'un a transformé le carnet d'ordres du Bitcoin en jeu vid��o. Un vrai champ de bataille en 3D 🤯
Les acheteurs qui chargent d'un côté, les vendeurs de l'autre, les baleines qui débarquent comme des gros chars, les liquidations qui se font dégommer en direct sur le terrain.
Le pire c'est que c'est le vrai order book, en live. Et moi je suis là, à 8h du mat, à tourner la caméra pour regarder mes liquidations préférées se faire éclater.
Dix minutes de perdues et zéro regret.
C'est débile, c'est génial et je pouvais pas garder ça pour moi.
⚡️Eventfulness is a property of synchronized time, and synchronization is the thing that died.
An event is what happens when multiple people’s attention occupies the same moment.
School’s real product was never education; it was thousands of clocks forced into alignment, the same bell, the same hallway, the same Tuesday.
Inside synchronized time, encounters compound automatically, because everyone is already on the field.
Civilization understood this for ten thousand years and built nothing but synchronization machines: sabbath, market day, harvest festival, the factory whistle, the parish calendar, the league night. Those devices were never decoration on top of life. They were the generators of it.
The last half century dismantled every one of them, on purpose, and called it freedom.
Flexible hours, personalized schedules, on-demand everything, remote work, the feed.
Each convenience was purchased by desynchronizing from other humans, one device at a time, until the average adult now lives in fully private time, a schedule shared with no one.
The feed completes it by offering communion’s corpse: other people’s moments, watched alone, after they happened. Asynchronous intimacy, which is to say none.
Beneath that runs the memory mechanism, which is why the days blend.
Episodic memory keys on social salience; the brain files a day as an event when other people witnessed it. The same self, repeatedly seen by the same others, is how a person stays distinct to themselves.
Remove the witnesses and days stop
compressing into narrative. Nothing files, so nothing is recalled, so time evaporates in bulk. Weeks becoming months is the direct phenomenology of unwitnessed time. The parking lot feeling is what a nervous system reports when it is no longer being observed into existence.
Under that, the oldest layer. The organism is built for the band, thirty to a hundred fifty people in permanent ambient co-presence, and it reads the band’s absence as mortal danger. That is the source of the low-grade dread, the sense that something is wrong even when nothing is.
Solitary confinement is torture by the same mechanism at higher dose. Modern adulthood administers the dilute version to entire populations and calls the symptoms a mental health crisis.
School felt like a moving train because school was the last band a person ever belongs to by default.

We’re not entering games anymore.
Games are entering our reality.
This isn’t about better graphics—
it’s about who gets to create the world.
From developers → to everyone.
The barrier is gone.
Now only one question remains:
What will you build?

🔥THE BALLAD OF KING SAYLOR: A BITCOIN ODYSSEY🔥
While the public was busy getting spiritually anesthetized by CPI revisions, Netflix sludge, and 4.3% yield savings accounts marketed like the Second Coming, Saylor was in the corner reverse engineering monetary history like a Byzantine archivist with a death wish for weak balance sheets.
He understood the game at the level that makes normal executives break out in hives.
I’m talking FULL-SPECTRUM CAPITAL WARFARE, you little RAT CHILDREN.
He looked at fiat and saw a mathematically elegant landfill.
He looked at Bitcoin and saw PERFECTED MONETARY ENERGY.
He looked at corporate debt markets, equity premiums, convertibles, preferreds, volatility, reflexivity, and institutional mandate creep, then stitched the whole thing together into a flying treasury abomination that eats dollars and excretes scarcity.
That’s why the average portfolio manager sounds like a frightened zoo animal when they talk about him.
Their entire worldview depends on the assumption that everyone important will remain spiritually castrated forever, politely clipping coupons while the currency dissolves around them.
Then Saylor appears, eyes glowing like a Federal Reserve exorcism, and starts using public markets as an industrial vacuum hose for the hardest asset on Earth.
He built a recursive capital extraction engine pointed directly at the rotting corpse of twentieth century finance.
Every quarter he looks less like the classic executive chairman and more like the final boss of debt monetization, some leather-bound archon of accounting arbitrage who figured out that if the system is stupid enough to subsidize its own replacement, the moral thing to do is hit the gas until the walls scream.
Fifty years from now, textbooks will describe him with the kind of language usually reserved for conquerors, heretics, and men who accidentally discovered new physics while trying to get rich.
Because that’s what this is.
He identified that the global monetary order was a delirious paper cult and responded by turning a sleepy software firm into a civilization-scale battering ram.
Saylor is what happens when one man realizes the bond market is full of domesticated prey, the equity market is full of hypnotized accountants, and Bitcoin is the exit hatch from a burning asylum.
And the funniest part is he explained the whole thing out loud, in plain English, for years, while millions of midwits smirked from beneath their little CFA certificates like medieval doctors laughing at a telescope.
YOUR PHONE HEARD YOUR THOUGHTS.
You didn’t search it. You didn’t say it out loud.
You thought it.
And 20 minutes later, it showed up in your feed.
Here’s what’s actually happening. 🧵
To astrophysicists only factors of 10 and π ~ sqrt(10) matter.
My undergrad thesis was on cosmic ray production from white dwarfs and I found a factor of π^4 that the person the year before me working on an earlier version of the problem had forgotten to include. Just a couple of factors of 10, but in the wrong direction.
🚨 Simulation Theory: The Double Slit Experiment proves particles act like waves until observed then they snap into particles.
What if our reality only "renders" when we're looking, just like a video game optimizing resources?
Check out this episode from The Why Files breaking it down, tying it to Simulation Theory. Are we in a sim?
This could be the key to unlocking the true nature of existence!
The Why Files video did a great job on explaining the Double Slit Experiment & Simulation Theory
