AGI Is Here. Do You Have a Ticket?
When the strongest AI is not expensive but simply unavailable, the world starts converging on digital feudalism. And the window to act is narrowing.
Can You Distill an Expert?
Polanyi's tacit knowledge explains the 70% ceiling of AI agents: real intuition, feel, and judgment do not serialize cleanly. They grow, if at all, through practice.
Yes, I Use AI to Write
AI is a multiplier. It amplifies depth and mediocrity alike. In an age where answers are cheap, questions are the real currency. There is nothing to hide about writing with AI.
Local AI's Inflection Point: 2027

Anthropic's new research gives us the first direct look at causally steerable "emotion vectors" inside a large language model. That should change how we think about AI.

Why 'Vibe Coding' Should Be Translated as 'Xieyi Programming'
The best Chinese translation of "Vibe Coding" is not a literal one. "Xieyi Programming" captures the shift from line-by-line control to intent-first coding, where AI handles the details.
360 Shipped Its Wildcard TLS Private Key Inside a Public Installer
