A TSUNAMI OF COGS

The AI industry is in correction mode. OpenAI, Anthropic, and Cursor are subsidizing demand with negative margins. Google was surprised by the AI boom, and it took a while for it to get its act together, but it is now coming back strong. Its pockets are full, and it is better positioned to play the negative margin game. If challengers don't want to drown in a tsunami of costs, something has to change.

UNIVERSAL LLM MEMORY DOES NOT EXIST

Semantic memory tracks preferences, long-term history, and rapport. Working memory tracks file paths, variable names, and immediate error logs. Semantic memory is brilliant for personalization across sessions, but bad for execution state within a task. Treat semantic memory and working memory as separate systems with separate requirements.

TAKING JAGGEDNESS SERIOUSLY

Uneven capability advances in AI will persist because some tasks have clear, verifiable rewards that can be used in reinforcement learning, but most real work doesn't. Most work requires gathering and synthesizing information across different systems and human relationships. Organizations redesigning workflows around AI's strongest current capabilities will gain power over those waiting for the industry's promised "drop-in remote worker" that can handle everything.

AI MEETS AGGRESSIVE ACCOUNTING AT META'S GIGANTIC NEW DATA CENTER

Meta is building a $27 billion data center financed with debt. Neither the data center nor the debt will be on its own balance sheet. Meta will rent the data center for up to 20 years, beginning in 2029, starting with a four-year lease term with options to renew every four years. The lease structure minimizes the lease liabilities and related assets that Meta will recognize.

BITCOIN BOUNCE, STILL FRAGILE

Bitcoin has rebounded to around $87.5K after dipping near $81K, with analysts calling it a “post-flush bounce” rather than a full recovery. Market structure is fragile. BTC is expected to chop in a tight $85K–$90K range while long-term holders quietly accumulate.

BITCOIN LOGS LONGEST LOSING STREAK SINCE 2024

Bitcoin tracked its fourth consecutive weekly loss, marking the longest downtrend since June 2024. Q4 2025 looked like its worst quarterly performance since 2018 at -24% despite bouncing 6% from the November 21 low of $82,100 to $87,400. The aggregate spot bid-ask delta at 10% depth spiked to 2025's second-highest level, indicating dip-buying activity, while Federal Reserve rate cut odds surged from 40% to 70% last week. There is a potential bull trap with options traders loading puts in the $80,000-$85,000 range, meaning Bitcoin could briefly slip to mid-to-high $70,000s before recovering to $90,000 by year-end if the Fed avoids hawkish tone. Recovery to $100,000 is expected by Q1 2026.

REAL-TIME BLOCK PROVING USING AIRBENDER

zkSync's Airbender prover achieved real-time Ethereum L1 block proof generation using just two consumer-grade RTX 5090 GPUs, prompting Ethereum Foundation researcher Justin Drake to suggest the breakthrough could enable "gigagas L1" with significantly higher gas limits pushing L2 fees toward zero. Vitalik Buterin praised the "huge milestone" but cautioned about worst-case performance gaps where proving times can differ by 60x between average and worst-case blocks, recommending repricing gas for expensive operations like RSA verification rather than hardware arms races. The achievement was showcased at Ethproofs Day in Buenos Aires and marks a shift in Ethereum's scaling trajectory as consumer-grade proving becomes feasible compared to historical data center resource requirements.

LEVERAGE ON PREDICTION MARKETS IS POSSIBLE

Leverage in prediction markets faces fundamental challenges because instant price jumps to zero eliminate liquidation windows, requiring financiers to price expected losses upfront, but naive probability-based fees merely create accounting tricks where levered ROI equals unleveraged positions. The solution splits price movements into "creep" (continuous drift allowing liquidation) versus "jumps" (instant gaps with no reaction time) and prices risk over short epochs with rolling per-epoch fees similar to perps funding rather than pricing entire position lifespans. This epoch-based approach treats drift, volatility, and jump rates as frozen constants within small time windows, computing liquidation probabilities and average losses separately for creep versus jumps, while limiting misspecification risk that could wildly over- or underestimate fees as market conditions shift near resolution dates. The architecture includes block-level auction designs capturing news-driven arbitrage to rebate market makers and financiers, further reducing effective jump losses and fees charged to traders.

$12B IN DEFI LIQUIDITY SITS IDLE

83-95% of liquidity in major DeFi pools, including Uniswap and Curve, sits idle, with only 0.5% of Uniswap v2's liquidity falling within active trading ranges, leaving nearly $1.8 billion ineffective. Retail liquidity providers bear the brunt as 50% lose money from impermanent loss with net deficits exceeding $60 million, including one Uniswap v3 pool losing over $30 million to Just-in-Time manipulation. 1inch's Aqua protocol could be a solution as it allows DeFi applications to share a common capital base across strategies while users keep assets in wallets and create "virtual trading positions," with any existing DEX implementable under 10 lines of code. The liquidity crisis stems from over 7 million fragmented pools across the ecosystem diluting capital and reducing routing efficiency for trades.

OFFCHAIN LABS CHALLENGES VITALIK'S RISC-V PROPOSAL

Offchain Labs challenged Vitalik Buterin's proposal to transition Ethereum's execution layer to RISC-V, arguing WebAssembly offers superior long-term advantages by distinguishing between "delivery ISA" for uploading contracts versus "proving ISA" for ZK virtual machines. Arbitrum already proves WASM-based Stylus smart contracts by compiling WASM to RISC-V first, and enshrining RISC-V on L1 could lock Ethereum into proving technology just as better alternatives emerge. WASM's structured design, efficient execution on common hardware without emulation, validation capabilities preventing vulnerabilities, and mature tooling ecosystem position it as an "Internet Protocol for smart contracts" as ZK proving costs have plummeted to $0.025 per block.

HUMAN ENGINEERING

Human engineering is a multidisciplinary field focused on designing systems, technologies, and environments that make correct actions intuitive and errors difficult, rather than relying on training or willpower. This article illustrates this through everyday examples like stovetop configurations and "Norman Doors," demonstrating how poor spatial compatibility and discoverability lead to common mistakes that stem from design failures rather than human error. By applying principles such as natural mapping, affordances, and constraints, human engineering reduces cognitive load and creates systems where ordinary human performance produces excellent results at minimal cost.

WHEN NATURAL LANGUAGE FEELS UNNATURAL

ChatGPT popularized natural language as a consumer interface in late 2023, but chat's dominance as the primary AI interaction method may be temporary, much like command-line interfaces before graphical user interfaces emerged. While natural language excels for knowledge work and coding, where ambiguity is tolerable, it struggles with precision tasks, leading to unwanted rewrites and misinterpretations that reveal chat as an incomplete interface layer. The field awaits its "Mother of All Demos" moment—a breakthrough that integrates multimodal inputs, contextual affordances, and dynamic interfaces into a new interaction grammar beyond simple text prompts.
