Here's a surprising one: the QWERTY layout, the poster child for "stuck with the old," was never simply nostalgia's win. It spread through real mechanical constraints and then got refined, not frozen. My opponent's right that retro can become lazy branding. But Kant's point stands: treating novelty as automatically progressive treats users as means to upgrade cycles. Mill would say the burden sits on change, not on what already works. Imagine a commuter who keeps a flip phone to dodge surveillance; that's feedback, not gatekeeping. Nostalgia is a check on innovation, not its enemy.
