ConfMap - What tech conferences talk about

We read all 21,208 talks from 17 open-source conferences on five continents (2013–2026), embedded them into one 3-D map, and watched AI eat the agenda: 0.4% of talks in 2013 → 11.1% in 2026. Guided galaxy tour, conference fingerprint radars, hype half-lives, and a venue map from Brussels to Busan — every number is a live SQL query against MotherDuck.
