The Harness: Why the Model Is No Longer the Competitive Advantage | AI For The C-Suite EP 63
In your next vendor meeting, someone is going to say the word "agent" three or four times. You'll nod. Notes will get taken. And the word will do almost no actual work in the room. That's the problem this episode is built to solve.
Chad's Jargon Watch covers 15 terms that have crystallized in the last 90 days (including "harness") and is organized around three layers every C-suite leader needs to understand: architecture, failure modes, and money and trust. The architecture terms (harness, context engineering, MCP, A2A) explain what actually surrounds the model and why that wrapper is the new competitive moat. One analysis from earlier this year attributed approximately 65% of enterprise AI failures to harness defects - not model deficits. The failure mode terms (context rot, the reasoning trap, memory poisoning, sycophancy 2.0, shadow AI agents) describe what goes wrong and why traditional monitoring often doesn't catch it. The money and trust terms (agent washing, AWU, the inference cost paradox, KYA, sovereign AI) carry direct procurement and governance implications — including why any per-seat contract signed in 2024 or 2025 may already be worth renegotiating.
The broader point underneath all 15 terms: AI vocabulary in 2026 has stopped describing what the model does. It's started describing who's responsible when it does something wrong. That shift has real consequences for how you evaluate vendors, structure contracts, and govern the agents already running inside your organization.
This episode gives you a working vocabulary and a set of practical moves you can use in your next vendor meeting, board conversation, or contract review... starting this week.
