The Triple Engine Collapse: Why YC's 16 Startup Prompts Are a Map of What AI Just Made Buildable
Workday cut 8.5%. Atlassian laid off 1,600. Klarna said AI could replace 700 agents. The layoff headlines are real — but they're reading the wrong signal. The three engines that protected legacy SaaS for thirty years just broke. YC mapped what comes next.

Inside Garry Tan's G-Brain: The Open-Source Repo YC Wants Every Company to Clone
Tom Blomfield told founders to build 'Garry's G-Brain, but for every business in the world.' We opened the repo, read the code, ran the benchmarks, and found four architectural bets that rewrite how agents should handle memory, routing, and self-maintenance.

Habsburg AI: What Happens When Models Train on Models
The internet is running out of human-written data. Every frontier lab's answer is the same: train models on data the models generate. It's the most consequential bet in AI — and the conditions that made it work on a Go board are, at best, partial for language.

I Built Real-Time AI Conversations for NPCs. Here's Why It's the Wrong Architecture.
Two AI agents, talking to each other in real-time. They don't know what the other one will say. There's no script. It works. And it's also completely the wrong way to build this for a game.

Hermes Agent Technical Review: Safety via Transparency
Hermes is one of the most architecturally interesting AI agents I've reviewed this year. The maintainers chose a bold philosophy: 'Safety via Transparency'. But is transparency actually a safety control? I took it line-by-line through the OWASP Top 10 for LLM Agents to find out.
