Great talk! The DBMS ecosystem is badly lacking in sustained revolutionary efforts. It's understandable - even with OSS accelerators like Calcite and DataFusion the entry costs for addressing the inertia of SQL are extreme. Luckily DuckDB proves that revolutions here are still possible, and welcome!

The theme of CMU's ongoing Future Data Systems seminar series is "what should a database system look like in the future to handle more of our past so we never forget" - clearly I'm biased, but the answer has to be @xtdb.com !
