Leerob lectured at Stanford CS146S on how always-on, proactive agents work, calling this architecture the future of coding — likening Cursor Projects to "Grok Bot for Coding" with more visibility into subagents and context, or GarageBand vs. Logic Pro for music.

- 2:35 How we got here
- 6:13 What changed in the models
- 10:06 Inside an always-on agent
- 18:07 The harness
- 27:26 Context engineering
- 34:26 Where this is going
