We must use innovation to ramp up our social safety net

Imagine the store of the future. You walk into an immaculate, brightly lit room stocked from floor to ceiling with the freshest food on glossy shelves. Instead of the typical store cashier checking out your kale chips and kombucha, the store is dotted with technology to track you.

Weight sensors are in the shelves to track products, cameras eye your every movement, and each item you pick up and put into your bag or backpack is automatically scanned. And then you walk out and instantaneously get billed for the exact items you selected.
