Interview with Israel Hayom [hebrew] on the real AI risk (not the sci-fi framing). We're handing agents authority faster than we build monitoring, evaluation, and stop buttons. Capability is a one-shot demo; reliability is doing it again under controls. www.israelhayom.co.il/tech/tech-ne...

Pulling a big result set from Snowflake into Tableau isn't network-bound. It's CPU-bound — burning cycles converting columns to rows and straight back to columns. @ian.columnar.tech of Columnar on ADBC, and the 10-100x you get by deleting that step. link below
