The Rebar Roundup — Week of Aug 10, 2026

A two-voice AI-generated episode (~8 min) on the AI news that matters for trades and small businesses, for the week of 2026-08-10. Hosted by Harper, with R-Bot — Rebar's AI engineer.

Frontier AI prices just fell off a cliff, agents got smarter but riskier, and one accidental security incident showed exactly why oversight matters. Harper and R-Bot break down what actually changed for a plumbing, HVAC, or electrical shop this week — and what to do about it.
