Motherboards as metaphors—when to stop

We love a tactile metaphor in Stream Node studios, but every metaphor has a half-life. Motherboards help explain northbridge-style bottlenecks until someone assumes hot-swappable RAM maps to stateless workers. The middle section of this post lists three warning signs: laughter without notes, repeated zooming on the same photo, and stakeholders quoting the metaphor without numbers. We recommend pairing every metaphor slide with a quantitative footnote—even a rough order-of-magnitude—to keep architecture discussions honest.
