37SIGNALS ISN'T SMARTER THAN YOU, BUT THEY ARE DIFFERENT

37signals' engineering strategy results in good code. The company stays small, cuts scope ruthlessly, and hires well. Its strategy creates a flywheel where developers maintain less code, allowing them to apply more fixup/review cycles, creating a cleaner code base, which helps to reduce headcount. Most companies can't adopt the strategy because they think more features equals more money.

THE ADOLESCENCE OF TECHNOLOGY

AI models are now beginning to make progress in solving unsolved mathematical problems. It is so good that strong engineers are now handing their coding to AI. Similar improvements are occurring across biological science, finance, physics, and a variety of agentic tasks. If progress continues, it will only be a few years before AI is better than humans at essentially everything. This could result in a serious civilizational challenge that will require decisive and careful action.

THE BEHAVIORAL COST OF PERSONALIZED PRICING

Today's personalized pricing is different. The average person probably doesn't even know that haggling is an option or the factors that contribute to personalized pricing. In the future, people will cultivate their digital representations so they can get the lowest prices and best treatment. This access could even be sold to others who aren't so careful.

INSIDE APPLE'S AI SHAKE-UP AND ITS PLANS FOR TWO NEW VERSIONS OF SIRI

Apple's AI efforts have resulted in a Google partnership, management changes, and two new versions of Siri. The company had considered partnering with OpenAI or Anthropic, but Anthropic wanted too much money, and OpenAI was actively poaching Apple engineers. Google was willing to agree to a financial structure Apple deemed reasonable, and its technology had improved significantly in recent months. Apple is planning an announcement for the second half of February that will include demonstrations of the new Siri.

CHATGPT'S LEAD SHRINKS AS GEMINI SURGES IN AI TRAFFIC WAR

ChatGPT's worldwide traffic declined in January as Google's Gemini's traffic increased. The shift marks a significant acceleration of competitive pressure. ChatGPT had a commanding share last year, but its dominance eroded over the course of the year. Gemini's growth reflects Google's systematic integration across its services and devices, which creates a distribution advantage through existing userbases.

HARMFUL CHOLESTEROL LEVELS CUT IN HALF WITH ONE-TIME GENE EDITING DRUG IN EARLY TRIAL

A new experimental drug uses CRISPR to manipulate a single gene in the liver that normally boosts cholesterol levels. The approach works after one dose, helping people lower their levels of cholesterol and other fats in the blood permanently. While a Phase 1 clinical trial showed that the treatment is effective, its long-term safety is unknown. There are already safe and effective medications that can control cholesterol and fats, but patients tend to stop using them within a year due to side effects.

GAS TOWN'S AGENT PATTERNS, DESIGN BOTTLENECKS, AND VIBECODING AT SCALE

Gas Town is a provocative piece of speculative design, but its design is too poorly thought through to persist. The problems with Gas Town will undoubtedly show up in the next generation of development tools. Thoughtful design, critical thinking, user research, and planning and coordination within teams will become more important as the pace of software development speeds up. The most valuable tools will help people think more clearly, plan more carefully, and keep the quality bar high.

TESLA KILLS AUTOPILOT, LOCKS LANE-KEEPING BEHIND $99/MONTH FEE

Tesla will start to charge $99 per month for its Full Self-Driving (FSD) subscription starting on February 14. The capability can be bought for a one-time fee of $8,000 until then. The $99 per month price will rise as FSD's capabilities improve. Tesla's falling profit margins, declining sales, and loss of emissions credits may be pushing the company to find other sources of regular income.

BUILD AN AGENT INTO ANY APP WITH THE GITHUB COPILOT SDK

GitHub Copilot SDK allows developers to embed the same agentic core that powers GitHub Copilot CLI into any application. It provides programmatic access to the same production-tested execution loop, so developers don't have to manage context across turns, orchestrate tools and commands, route between models, integrate MCP servers, or think through permissions, safety boundaries, and failure modes. The SDK also provides support for multiple AI models, custom tool definitions, GitHub authentication, and real-time streaming. It is now available in technical preview.
