Google Glass
The future was on your face. Unfortunately, it didn't help your looks.

Quick Bits
What It Was
Google Glass was an early face computer that put notifications, camera features, and digital overlays right in your line of sight. It was sold as the future, which sounded exciting right up until people had to stand next to it in public.
Why It Mattered
It shoved augmented reality, wearable interfaces, and tech-in-your-face social boundaries into the mainstream conversation all at once. Even people who never wore it understood it was trying to change how humans relate to screens.
Why It Did Not Catch On
It was expensive, socially awkward, and wrapped in privacy concerns that made wearing it in public feel like a great way to get side-eyed.
Glass matters less as a hit product and more as a giant caution sign for the wearables industry about timing, trust, and not freaking everybody out.
