A spacecraft&rsquo;s ground software loses a probe because pound-force and newton were conflated. A billing pipeline issues refunds in cents where the ledger expected dollars. An engineering dashboard reports a beam&rsquo;s deflection in millimetres and a reviewer signs off because the number looks plausible. Every one of those bugs is a <em>type</em> bug: the program had a <code>double</code> where it needed a <code>Length</code>, and <code>double</code> never objects.</p>
