A Western Scholar's Field Notes from Visiting Chinese AI Labs: Humility, Openness, No Philosophy, Just Wanting to Train Better Models

An Impressed Western Scholar's Observations from a Tour of Chinese AI Labs: Humility, Openness, and Pragmatism A visiting Western academic's key takeaways from touring numerous Chinese AI companies highlight striking differences from the US ecosystem. Researchers in China displayed deep humility, frequently praising competitors like DeepSeek with genuine admiration. They operate in a remarkably open and collaborative atmosphere, often sharing research publicly, contrasting with the more guarded, zero-sum competition perceived in the West. The primary focus is intensely pragmatic: training better models. Philosophical debates about AI's societal impact or consciousness are largely absent; the drive is purely technical. Researchers are young, often PhD students working in industry, and are highly online and tool-savvy. Their passion is palpable when users engage with their models. Public sentiment also differs, with Chinese citizens showing greater optimism about AI's benefits compared to Western skepticism. While major closed-source players exist, the prevalence of open-source models fosters a unique cooperative spirit. The visit left the author optimistic about the future of open AI research and hopeful for increased international collaboration.

Wall Street’s Ethereum Expansion Gains Speed As Tokenized Treasuries Top $8 Billion

The market cap of tokenized U.S. Treasuries on Ethereum has reached an all-time high of approximately $8 billion, doubling in value over the past six months. This growth is driven by products from multiple institutions including BlackRock’s BUIDL, Franklin Templeton’s iBENJI, and offerings from WisdomTree, Ondo Finance, Centrifuge, and Superstate. Ethereum dominates this space, holding far more value than competitors like BNB Chain, Solana, Stellar, and the XRP Ledger. These tokenized assets are not just held as investments; they are actively used as yield-bearing collateral within decentralized finance (DeFi) protocols, providing liquidity and functionality beyond traditional bonds. While this marks a significant milestone, the $8 billion total remains a small fraction of the broader $27 trillion U.S. Treasury market. Regulatory frameworks for blockchain-based securities are still under development by financial authorities.

S&P Call Options Explode to Record $2.6 Trillion Volume: The Crash Risks Behind a Frenzied Gamble

The article discusses a record-breaking $2.6 trillion in S&P 500 call options traded in a single day, which the author sees as a sign of extreme market speculation. The piece explains that retail traders are aggressively buying these options, betting on further price rises. To hedge their risk, market makers who sell these options are forced to buy massive amounts of the underlying stocks, creating a self-reinforcing cycle known as a "gamma squeeze" that pushes prices higher independently of fundamentals. The author warns that this dynamic is unsustainable, comparing it to a casino or past bubbles like GameStop and Tesla. The risk, they argue, is that when these options expire or positions are unwound, the buying pressure could reverse into violent selling pressure, potentially triggering a sharp market decline. While expressing long-term optimism for U.S. stocks, the article cautions heavily leveraged or speculative investors about the inherent dangers in the current market environment.

The US Stock Market in 2026, It's Almost Too Easy, and That Makes Me Nervous

The U.S. stock market's performance in 2026, particularly in the semiconductor memory sector, has generated significant returns that make some investors uneasy. A popular sentiment contrasts the perceived skill required for success in China's A-shares with the apparent ease of profiting from simply holding U.S. stocks. The primary driver is a global memory chip boom. Stocks like Micron, Seagate, Western Digital, and especially SanDisk (spinning off from WDC in 2025) have skyrocketed, with some gains exceeding 500% or even 2200%. Korean giants Samsung and SK Hynix, dominating their domestic index, have also surged. This rally is fueled by an AI-driven demand surge for memory like HBM (High-Bandwidth Memory), critical for AI chips. Tech giants like Google and Microsoft are placing massive, "unpriced" orders, while analysts continuously upgrade forecasts. SK Hynix reported its 2026 HBM capacity is already sold out. Despite record profits and sky-high margins (e.g., SK Hynix's 72% operating margin), major memory manufacturers are deliberately restricting capital expenditure and capacity expansion, controlling over 90% of DRAM supply. This supply discipline sustains high prices but draws parallels to cartel behavior. The situation presents two narratives. The bullish case sees AI demand as a structural, long-term shift with a prolonged supply gap. The bearish case, exemplified by short-seller Citron's failed bet against SanDisk, warns of a classic commodity cycle where prices eventually crash rapidly, as seen historically. The irony is noted: while retail investors marvel at easy gains, insiders like Western Digital are selling SanDisk shares at a 25% discount. Ultimately, the high cost of memory in consumer devices feeds into the record profits of memory companies and the soaring stock prices, leading many to question the sustainability of a market where making money seems "as easy as breathing."
