10/ So what does that mean for you? Don’t chase hype. Don’t assume permanence. Don’t worship early winners. Study the pattern. Because the survivors are rarely the loudest. They’re the ones who adapt when the crash comes.

9/ But here’s the twist. During these booms, the real opportunity is not guessing which company survives. It’s learning the system while it’s chaotic. The early car era built engineers. The dot-com era built software talent. This era is building AI-native thinkers.

8/ Most of what looks dominant right now will not survive. Not because the ideas are bad. Because competition compresses margins. Capital dries up. Standards consolidate. A few platforms win.

7/ Here’s what that tells us about today. We are living through another boom. AI. Creator economy. Performance tech. SaaS tools. Apps for everything. You are watching the 1,800-car-company phase in real time.

6/ This pattern has a name. Joseph Schumpeter called it “creative destruction.” Innovation does not gently upgrade society. It wipes the board.

5/ In 2000, the NASDAQ crashed nearly 78% from peak to trough. Hundreds of public internet companies collapsed. Most startups vanished. A small percentage survived and became giants like Amazon and eBay. Again, 80–90% gone.

3/ By the 1920s, most of them were gone. Bankrupt. Acquired. Forgotten. Today, only a handful of early-era names survived in recognizable form, like Ford and GM. Over 90% disappeared.

2/ In the early 1900s, America was OBSESSED with cars. Anyone with a machine shop and a dream started a company. Steam cars. Electric cars. Gas cars. It was chaos

Moral of the story: Your brain thinks it's protecting you, but sometimes it's just holding you back from throwing absolute gas. Training is just expensive therapy to convince your neurons to chill out. The End.

So yeah, spring training isn't just about arm strength or conditioning. It's about negotiating with your own nervous system like you're trying to talk a bouncer into letting you into a club. "Come on, man. Just five more mph. I promise I won't tear anything."

It's like when you're holding a plank and shaking like a leaf, convinced you're about to collapse—but then you hold it for another 30 seconds because your coach screamed at you. Your body had more in the tank. Your brain was just being dramatic.

The wildest part? Sometimes a pitcher will have a massive velocity jump not because he got stronger, but because his brain finally stopped panicking. One day he's throwing 92. Next week? 96. Same arm. Different level of neurological trust.

Pitching coaches know this. They don't just work on mechanics—they work on tricking your brain into unlocking more horsepower. "Throw this weighted ball." "Now throw a lighter ball." "Now throw a regular ball but pretend it's light." Your brain gets confused and accidentally lets you throw harder.

This is why spring training exists. It's not just about getting in shape—it's about convincing your brain to stop being such a coward. Every bullpen session is basically exposure therapy for your central nervous system.

J Keith Hall MD @jkhallatl.bsky.social · 04/04/2026

So when a pitcher throws 92 instead of 97, it's not because his arm CAN'T throw harder. It's because his brain is standing there like an overprotective mom yelling, "SLOW DOWN OR YOU'LL HURT YOURSELF." Except the mom is inside your skull and you can't argue with her.

Scientists call it neural drive—basically, how hard your brain is willing to let your muscles fire. And your brain? It's not trying to make you a Cy Young winner. It's trying to keep your rotator cuff from exploding like a cheap piñata.

Here's the thing nobody tells you: your brain is a paranoid control freak that doesn't trust you with your own arm. It's like having a Ferrari with a built-in governor that caps you at 55 mph because "safety regulations."

Picture this: A rookie pitcher shows up to camp. He's 23. His arm is pristine. His fastball velocity? Ninety-two miles per hour. The pitching coach pulls up his biomechanics report and says, "According to physics, your arm should throw 97." The pitcher blinks. "So... where are my other 5 mph?"

Let me tell you about the most frustrating conversation happening in every MLB spring training camp right now—and it's between a pitcher's brain and his arm. 🧵

Moral of the story: • Your face is a snitch. • The nervous system doesn't stay quiet when it's struggling. • If you look in the mirror and think "Huh, that's weird," your body might be trying to tell you something. Listen to your face. It knows things.

So what did I do? I started sleeping more. Cut back on caffeine (a little). Did some breathing exercises that made me feel like a yoga instructor having an existential crisis. And slowly—SLOWLY—my face went back to normal.

And the wildest part? Most people don't even notice it's happening. They just feel exhausted, irritable, maybe a little "off." But they don't realize their face is literally trying to tell them something. It's like your body's passive-aggressive way of saying "Hey, fix this."

Your vagus nerve—the main highway of your parasympathetic nervous system—controls a ton of facial muscles. When it's not functioning properly, things get wonky. One side of your face might droop slightly. Your smile pulls to one side. You look vaguely like a cartoon villain.

J Keith Hall MD @jkhallatl.bsky.social · 03/04/2026

Scientists call this "facial tone asymmetry," which sounds way fancier than "your face is broken because you haven't slept in three days and live off coffee and spite." But that's essentially what it is.

When your nervous system is fried—stressed, overworked, under-recovered—it doesn't just mess with your mood or energy. It literally starts broadcasting dysfunction through your facial muscles. A drooping eyelid here. An asymmetrical smile there.

J Keith Hall MD @jkhallatl.bsky.social · 03/04/2026

What I was experiencing was my nervous system basically screaming at me through my face. Because here's the thing—your face is connected to your autonomic nervous system like a dashboard is connected to your car's engine. And mine was flashing every warning light possible.

Now, being a doctor, my brain immediately went into differential diagnosis mode. Bell's palsy? No, wrong pattern. Stroke? Please, I'm too young and too stubborn. Horner's syndrome? Nah, pupils are fine. Then it hit me: I'm an idiot.

At first, I thought maybe I slept funny. You know, like when you wake up with pillow creases on your face that make you look like a topographic map. But then I noticed my smile was crooked too. Like my face was trying to go two different directions at once.

Picture this: I'm looking in the mirror one morning, half-awake, toothbrush dangling from my mouth like a broken antenna. And I notice something weird. My left eyelid is sitting about 2 millimeters lower than my right. Not a lot. Just... off.

Moral of the story: Search engines didn't give you access to all human knowledge. They gave you access to the version of human knowledge that fit their business model. And you never noticed, because the illusion of infinite information feels like freedom.

The wildest part? We used to worry about censorship. Banned books. Suppressed speech. But the modern version is quieter. You don't ban information. You just bury it on page eight of Google where nobody will ever find it.

And because it feels like choice—you typed the query, you clicked the link—you think you're in control. But you're not choosing what to see. You're choosing from what two companies decided to show you.

Here's the part that should terrify you: Most people don't even realize this is happening. They Google something, see the top result, and think, "Cool, I'm informed." They're not informed. They're algorithmed.

Now add AI into the mix. Google's rolling out AI-generated summaries at the top of search results. You won't even click a link anymore—you'll just read what the AI decided to tell you. One company. One algorithm. One AI. Zero transparency.

And it's not a conspiracy. It's a business model. Google makes money from ads. So pages that generate ad clicks rank higher. Pages that don't? Buried. The incentive isn't truth. It's profit.

This matters more than people realize. Journalists, researchers, students—everyone relies on search to find sources. If the search engine buries a study, hides a perspective, or boosts clickbait over credibility, that shapes everything downstream.

And before you say, "I'll just use DuckDuckGo or Bing"—Microsoft owns Bing. And even privacy-focused engines like DuckDuckGo pull results from... Bing. You're not escaping the matrix. You're just choosing which wire to plug into.

Here's an example: Search "climate change" and you'll get results shaped by what Google thinks you want to see. Search the same thing on a different account, different location, different search history? Different results. Reality isn't objective anymore. It's personalized.

Now you might say, "But the algorithm is neutral. It just ranks by relevance." Cute. The algorithm is designed by humans, trained on biased data, and optimized for engagement—not accuracy. It doesn't show you what's true. It shows you what keeps you clicking.

J Keith Hall MD @jkhallatl.bsky.social · 02/04/2026

Studies show 75% of people never scroll past the first page of results. So if Google decides your website doesn't rank, your article doesn't exist. Your research doesn't matter. Your perspective isn't real. One algorithm. One gatekeeper. One version of truth.

And here's the trick: You think they're finding you information. They're not. They're deciding what information gets to exist in your reality. Page one of Google might as well be the only page. Page two is where facts go to die.

Google and Microsoft control 97% of all search. Not 97% of search results. 97% of search itself. When you look something up online, you're asking one of two companies to tell you what's real.

Let me tell you about the most successful magic trick of the 21st century—convincing billions of people that two companies don't control what information exists. This is the story of how search engines became reality editors. 🧵
