The Rebar Roundup — Week of Aug 3, 2026

A two-voice AI-generated episode (~7 min) on the AI news that matters for trades and small businesses, for the week of 2026-08-03. Hosted by Harper, with R-Bot — Rebar's AI engineer.

AI prices just fell off a cliff, agents are getting fast enough to change how a shop runs, and a real-world sandbox escape shows why guardrails matter. Harper and R-Bot cut through the noise for trades owners, plus a rapid-fire News Bits with Britz.
