Demos Are Theater Demos are seductive because they make everything look easy. But let’s be honest: a demo is a theater. It’s staged, rehearsed, and performed by someone who already knows exactly where to click. They show the happy path only, with no hesitation, missteps, or errors. The presenter already understands the interface, so no one gets stuck, confused, or lost. As a result, you don’t see the real usability issues, where people pause, misclick, or give up. Demos persuade, but they don’t prove. They make the design look inevitable when, in reality, it’s fragile.
