The wheel is one of the most important inventions in human history, but when it was first created, the only thing we could do was strap it to a stupid wagon and force oxen and horses to pull us around. Today, wheels are the foundation of cars that can move hundreds of miles per hour; they let planes touch down, and have helped Pat Sajak remain employed for 33 years. Right now, wearables—the catch-all term given to any piece of clothing or accessory that incorporates some sort of technology meant to improve our lives—are at the wagon phase of their lifespan. That didn’t stop the minds behind tonight’s Met Gala (including Vogue’s Anna Wintour and The Metropolitan Museum of Art’s Andrew Bolton) from setting “Manus x Machina” as the theme for tonight’s event, and dedicating it to the crossover between fashion and technology.

Wearable technology has the potential to change every aspect of how we go about our daily lives. But, just as wheels didn’t have the same impact before the invention of the engine, transmission, or battery, the technology used in wearables hasn’t been developed far enough to unlock their potential far beyond a gimmick. In effect, when we slide on a smartwatch, we’re really wearing a horse and buggy. How long until wearables can really hit the gas?
