hypo generation is cheap finding tests to distinguish hypos is real work developing taste to quickly estimate the probability of different ontological planks prior to testing requires dedicated cultivation

i don't think he's dumb but the market is vicious and does not care if you are a visionary who predicted the trajectory of ai in 2020 or if you are a visionary who spectacularly called the housing collapse it is the devourer, it will eat anyone
Michael Burry might genuinely be the dumbest bear alive. He spent most of 2026 short the AI trade while it ripped higher. He shorted Micron at $1,051, pressed his Nebius short after a 34% earnings pop, and held Nvidia stock shorts through every beat. Then on September 28 he decided he wanted “more leverage” and covered his stock shorts. He swapped them for far out-of-the-money puts, and two weeks later folded most of those into broad index puts. Look at how the names he covered have done since: $CRWV: -33% $NBIS: -33% $MU: -17% $NVDA: -5% The AI cloud and memory crash he’d been predicting for a year showed up within weeks of him covering. And the switch made it worse. Stock shorts profit on every dollar the price falls. Puts struck far below the price, like his roughly $500 Micron puts, pay off only if the stock gets anywhere near that strike. Micron falling 17% from a thousand dollars barely touches them. The Nasdaq-100, where most of his short exposure now lives, is down only about 5%. He shorted CoreWeave, called it a meme-squeeze risk, covered it, and never bought the puts. It’s down a third since. Imagine being right about the AI bubble for a year, losing money on it for a year, and leaving the trade right before it finally pays. The market has absolutely no mercy. Not even for Cassandra.

Imagine if senate races involved bitter fights over how to manage the intractable India-Pakistan conflict. Everyone would see that’s insane. And that’s a conflict between two countries that account for nearly a quarter of world population.

Our investigators observed funds stolen by DPRK in last month's Bitget exploit commingling with funds stolen from Binance. We have a high degree of confidence that DPRK is responsible for the $6.4 billion hack of Binance.
We live in unprecedented times. But DPRK are up to their old tricks. We assess @binance hack for $6.4B was likely done by DPRK group TraderTraitor due to links to previous hack. Industry partners have already frozen ~$3B and we @chainalysis continue to follow all of the funds

After this tweet, a GPU provider we already wired $3M to called and asked for $5M more upfront. Said it’s now riskier. He tried to renegotiate a signed contract. Then banks we were in talks with cut their lending offers in half, saying their IC got scared. One reply moved capital markets against everyone building in this space except the people big enough to be immune to it. teapawt.org/elonmusk/status/211443…
Replying to @chamath
Pretty much. As of the past few weeks, debt markets have almost entirely shut off access to money for any company that doesn’t have substantial revenue independent of AI data centers. SpaceX closed $40B of debt for GPUs, but we’re investment grade and have Starlink & launch revenue. That means the 200+ neoclouds are going to see guppy-level death and consolidation. Some will make it through, but not many.

more than anything i'm curious if amd and intel diverge at all
I think Intel badly underestimated how quickly higher memory prices would hit PC demand and trigger an inventory correction. Those risks were already visible by the Q2 earnings call. Management acknowledged them, but still expected client revenue to hold roughly flat in Q3, supported by CPU inventory replenishment. That assumption now looks too optimistic. They should have set more conservative expectations for the client business. Still, Lip-Bu did make some encouraging comments. “We expect the industry to remain supply constrained throughout 2027 and into 2028.” “We now expect industry server CPU units to grow more than 30% in both 2026 and 2027.” “Growth would be higher in both years if additional industry supply were available.”

I don’t understand these PDF-length treatments of AI bubble scenarios. I don’t think a crash is coming but if it happens the only needed policy response is “don’t do anything.” Some investors will lose money and interest rates will fall. It’s fine. That’s my PDF.

BREAKING: Binance has been hacked with wallets across the Ethereum, Bitcoin, and TRON networks seeing outflows of -$5.7 billion. The hack includes $1.45 billion worth of Bitcoin and $875 million worth of ETH. If confirmed, this would mark the biggest hack in crypto history. We expect more information shortly.

We have new machines that revolutionize solving math problems boy I hope society doesn't rely on certain math problems being ultra hard for anything important

Subexponential algorithm for breaking elliptic curve discrete logarithm? If true It would challenge one of the central assumptions behind elliptic-curve cryptography (ECC), which protects cryptocurrency wallets, digital signatures and secure communications. github.com/bochum-crypto/sub…

Mao was terrible. The wrong side won the Chinese Civil War. The successors of Mao have been not as bad as he was, which is a low bar, but they've still been awful. Taiwan shows what China could and should be-- a multiparty capitalist democracy. Hopefully one day it will be one.

The economy *is* the lifeblood of the people.
just heard someone say "people are more important than the economy" and it occurred to me that some people genuinely believe that others care about the economy because they like numbers going up and not because it drives living standards for the population

RLHF is creating perverse incentives for incredibly long answers people will vote for the one that includes the different idea, so the models get trained to shotgun a bunch of ideas even if many of them are low quality similar to how "if you miss an argument you lose" led to the perverse development of speed talk displacing persuasive oratory in debate
