CONNECTOME PIONEER SEBASTIAN SEUNG IS BUILDING A DIGITAL BRAIN

Sebastian Seung, a neuroscience and computer science professor at Princeton University, was one of the researchers who helped create the first complete wiring diagram of a fly's brain. He has created a startup called Memazing to create the technology needed to reverse engineer the fly brain (and eventually more complex organisms) and create full recreations of the brain in software. The company's goal is to use an existing map of how nature has produced intelligence to create a new form of artificial intelligence. The startup is still in a very early stage and is in the process of raising funds, but the team has already begun work on the fly brain emulation and has started connecting a model to a simple robotics system.

NASA FINALLY—AND WE REALLY DO MEAN IT THIS TIME—HAS A FULL-TIME LEADER

Jared Isaacman, at 42 years old, is the youngest person to lead NASA. The agency has faced an extraordinarily difficult year. About 20% of the agency employees took buyouts or early retirements thanks to the Department of Government Efficiency. NASA is locked into a high-stakes race with China to return humans to the Moon, but the agency has to deal with an administration that sought to cut its budget by 24%.

2025 STACK OVERFLOW DEVELOPER SURVEY

Stack Overflow Developer Survey looks at the tools and technologies developers are currently using and the ones they want to use. This year's survey included questions about embedded technology tools and industry-sourced, community-vetted technology options. Python's adoption has accelerated significantly due to its ability to be the go-to language for AI, data science, and back-end development. Redis saw significant growth in usage, demonstrating the need for high-speed, in-memory caching and data structures. Docker is now a near-universal tool for cloud development. AI-enabled IDEs weren't able to topple the dominance of Visual Studio and Visual Studio Code - both have maintained the top spots for four years.

GOOGLE WORKS TO ERODE NVIDIA'S SOFTWARE ADVANTAGE WITH META'S HELP

Google and Meta are working together on a new initiative to make Google's Tensor Processing Units better at running PyTorch. The move is aimed at weakening Nvidia's longstanding dominance in the AI computing market. TorchTPU will remove a key barrier that has slowed the adoption of TPU chips. It will make existing infrastructure built using PyTorch software fully compatible with TPUs. Google is considering open-sourcing parts of the software to speed uptake.

THE SQUISHY NUMBER BEHIND THE RISE AND FALL OF ORACLE'S STOCK

Oracle is down 43% from its September high despite reporting $523 billion in "remaining performance obligations". About $300 billion of that comes from a five-year OpenAI contract, but analysts are skeptical that OpenAI, which only has ~$20B in annualized revenue, will be able to pay. Nvidia's stalled $100 billion OpenAI investment (announced in September but still unsigned) compounds the anxiety over the circular deals plaguing AI infrastructure.

YES, AGI CAN HAPPEN – A COMPUTATIONAL PERSPECTIVE

Current models vastly underutilize hardware: DeepSeek-V3 and Llama-4 achieve only ~20% FLOP utilization during training, and inference runs at single-digit utilization because autoregressive models are bottlenecked on loading weights from memory, not compute. Models we see today are also lagging indicators, trained on last-gen hardware that's unoptimized for the massive size of modern clusters and the latest training methods.

WHEN AGENTS ATTACK: HOW AI COLLAPSES AND REBUILDS MARKETPLACE MOATS

AI agents, like those launched by OpenAI, threaten marketplace moats by taking over discovery, transactions, and supply workflows, thus collapsing traditional marketing funnels. Marketplaces must adapt by optimizing brand experiences, personalizing interactions, and integrating supply to maintain value. Founders should focus on high-frequency markets, fortify customer connections, and explore new monetization strategies like subscriptions or data licensing to stay competitive.

WHAT ACTUALLY IS CLAUDE CODE'S PLAN MODE?

Plan mode is a feature in Claude Code that pauses execution until users approve of a plan. A plan in Claude Code is a markdown file written into Claude's plans folder by Claude in plan mode. Users can review and edit the plan before Claude executes whatever task it needs to. The tool brings in more complexity into the user interface, taking away some of the magic. It replicates something that natural language can already do, making the user experience a little less natural.

INSIDE CHINA'S 'MANHATTAN PROJECT' TO RIVAL THE WEST IN AI CHIPS

Chinese scientists have built a working prototype of an EUV lithography machine, the $250 million tool that only ASML knows how to make and which the US has blocked from being sold to China since 2018. A team of former ASML engineers reverse-engineered the machines in a high-security Shenzhen lab, with recruits given fake IDs and signing bonuses up to $700,000. The prototype hasn't yet produced working chips, but sources expect it will by 2028-2030.

SEC SAYS BROKER-DEALERS NEED TO MAINTAIN CRYPTO PRIVATE KEYS

The SEC's Division of Trading and Markets indicate that a broker-dealer can treat itself as having possession/control when it has exclusive access to the private keys needed to transfer the token. It also requires written policies and systems to protect keys from theft, loss, or unauthorized use, plus preparedness for operational events like network attacks, blockchain malfunctions, and hard forks, and processes to comply with legal orders to freeze/burn/seize assets. Custodians must monitor protocol/governance developments and reduce exposure if there are material security or operational weaknesses.

HOW BANKS LEARNED TO STOP WORRYING AND LOVE STABLECOINS

Fears of stablecoins causing immediate “deposit erosion” were overstated, as there is little evidence of deposit outflows tied to stablecoin growth because deposits are “sticky” because of the checking account's role as the hub for payroll, bills, credit, and mortgages. Rather than displacing banks, stablecoins can discipline banks into paying better rates and improving efficiency, expanding lending/intermediation and consumer welfare. The GENIUS Act addresses run/liquidity risk by requiring stablecoins to be fully backed by cash, short-term Treasuries, or insured deposits, with operational details left to regulators. The upside case is payments plumbing because stablecoins enable 24/7 atomic settlement, reducing cross-border delays and “trapped” liquidity.

THE RAMPING BOTTLENECK

Stablecoin ramps are the real adoption bottleneck as bank-funded ramping in the US/EU/UK can cost 0-0.3%, while parts of Africa can hit 15–20%. Global card on-ramp completion is ~21% (Africa ~6% and Asia ~7%), and cards are structurally mispriced for stablecoins because there's no product margin to hide MDR/chargeback risk.

BEWARE THE LOFTY PROMISES OF TRADFI FIRMS EMBRACING TOKENIZATION

TradFi's tokenization press releases hype 24/7 settlement and programmability, but they largely ignore the existential risk that permissionless onchain rails pose to their incumbent moats. These firms can't get the upside without meaningful cannibalization and mistakes along the way. If these firms fail, they'll use adoption carrots and regulatory sticks to push crypto toward permissioned, captured “crypto-like” systems.
