OpenAI Is Falling Out of Favor With Secondary Buyers (5 minute read)
OpenAI shares have dropped in value on the secondary market as investors pivot to Anthropic. Investors are, in some cases, unable to sell their shares. Meanwhile, buyers have indicated that they have $2 billion in cash ready to deploy to Anthropic. Anthropic and OpenAI don't allow investors to trade shares on secondary markets without permission, but access is still available on many platforms through mechanisms such as special-purpose vehicles.

Google's Quantum Crypto Paper Tells You Quite a Lot (22 minute read)
Google Quantum AI recently dropped a whitepaper with a headline finding that the cryptography that secures Bitcoin and most of the crypto ecosystem can be broken using fewer than half a million physical qubits on a superconducting architecture in about nine minutes. The company withheld the specific quantum circuit used in the name of responsible disclosure, but the paper constrains the search space so tightly that reproducing comparable circuits is well within reach for any serious quantum algorithms group. The qubit counts that make these cryptographic attacks feasible are roughly the same number of qubits required to make quantum-enhanced AI feasible. This suggests that the threat and capability of quantum computing will arrive roughly on the same timescale.

Economists on AI and economic growth and employment (1 minute read)
Economists and AI experts predict major AI progress, but there will be no dramatic break from economic trends. GDP growth rates will remain similar to today's despite a moderate decline in labor force participation. There will be significant economic impacts by 2050. It is predicted that by 2050, the labor force participation rate will be 55%, and 80% of wealth will be held by the top 10%, the highest disparity since 1939.

The Spec Layer (4 minute read)
Spec-driven development means writing durable intent down before implementation, using it to plan, build, check, and revise the work. The goal is to reduce execution freedom. Specs should be declarative, layered, and cheap to revise. When a rule can be enforced mechanically, move it out of the spec and into lint, schemas, tests, or the harness. Specs matter, but they're just one layer. The winning model puts a narrow interface between human intent and machine execution.

The Feedback Loop Is All You Need (17 minute read)
The most dangerous failure mode in agent-driven systems is silent drift - code that compiles and passes every test, but quietly violates the architectural assumptions that were thought safe. While humans can catch these mistakes through intuition, agents can't, so they need deterministic, immediate signals. This means tightening the feedback loop by shrinking the gap between a wrong change and a clear failure signal. Focus on feedback rather than chasing clever prompts.

What I Learned From Nearly 1,000 Interviews at Amazon (13 minute read)
The people who get hired are the ones who can tell a clear story about their work and capabilities and make the interviewer think, 'I want to work with that person'. This is a skill, and like any skill, it can get better with practice. Most people never practice because they don't think it is something they can prepare for. A little preparation here goes further than almost anything else you can do for your career.

Microsoft CFO's AI Spending Runs Up Against Tech Bubble Fears (13 minute read)
Amy Hood, Microsoft's longtime chief financial officer, has one of the hardest jobs in tech. The decision of how much to invest in AI without starving out other parts of the company or spooking investors with bottomless spending is a tough call, especially as projects about AI are educated guesses at best. While the industry consensus is to open the spigot for fear of missing out, Hood has kept a lid on costs, and Wall Street loves her for it. Huge AI investments have forced other companies to start burning cash, but Microsoft's margins have been largely stable.
