Spoke at Yurutech Beer Bash LT 2026.10 — Letting AI Drive a Mac with Computer Use

A write-up of my lightning talk at Yurutech Beer Bash LT 2026.10. I used the beer-bash setting to introduce Computer Use with a demo where Codex builds a single Keynote slide reading 'みなさん、乾杯！🍻' ('Cheers, everyone! 🍻' in Japanese) on macOS, then walked through the see / act / verify loop, the choice between browsing-only and OS-level computer use, and exploratory QA as a practical development use case. I also joined the after-party afterwards.
