Why Google Did Away with Project Ara
Project Ara was an ambitious venture to create a modular smartphone, featuring upgradeable components. And when I say ambitious, boy was it a moon shot.
It’s one thing to upgrade components in a desktop computer or a car, but the smaller the device, the trickier it is to engineer efficient connections between components whose bandwidth requirements and standards of communication vary wildly. Even notebook manufacturers struggle with this limitation as they attempt to engineer ever-thinner devices.
