Episode notes
Hackathon Origin Story
- Taylor built an agentic terminal at a hackathon two years before Gemini CLI became viable.
- He scrapped the early version because it was slow, expensive, and users weren't ready for a CLI then.
Coding Is A Small Part Of Work
- Developers spend far less than half their day writing code; most time goes to coordination and alignment.
- Faster build tools shift the bottleneck to consistency, design decisions, and team alignment.
Agent Manages My One-On-Ones
- Taylor used Gemini CLI plus a Workspace extension to clear and reschedule one-on-ones in minutes.
- The agent emailed, messaged, and managed his schedule end-to-end during that demo.
