That ratio is inverted from where the risk actually sits — and the gap is widening as agents move from demos into systems that do things on people&rsquo;s behalf.</p> <p>Let me try to explain why I think most of the industry is optimizing the wrong control.</p> <h2 id="the-obvious-part-first">The obvious part first</h2> <p>Prompt injection is real. It is not going away. Detection has its place — as a sensor, alongside other sensors, feeding a decision layer. I am not arguing against building detectors. I am arguing against the implicit claim, encoded in how budgets are being spent, that detection is the <em>decisive</em> control for agentic systems.</p>
