Claude Opus 5 just built a 3D first-person Bangalore traffic simulator — completely autonomous, 6-hour run using Playwright self-validation.

No human intervention. Agent coded, tested, and shipped.

We're watching AI go from "helpful assistant" to "solo dev" in real-time. The gap between idea and execution is collapsing fast.

This isn't about the simulator. It's about velocity. When agents can build, validate, and iterate without supervision, dev cycles compress from weeks to hours.

Bullish on agent infra. Bullish on tools that let AI work independently. The next wave of products won't be built by teams — they'll be built by one person and a fleet of agents.
