The human element

Digital services have human workers behind them, including ride-sharing businesses like Uber and Lyft, whose drivers have gone on strike demanding better wages as well.

Companies including Waymo, Daimler Trucks and Einride are just a few working on autonomous trucks that can drive and deliver goods with a person behind the wheel. Uber too is developing self-driving cars that can ferry passengers without needing a human driver, while Waymo is actually in trial on a driverless taxi service in the Phoenix, Ariz. metro area.

Retailers too are eyeing how robots can replace workers, including Walmart which is installing 3,900 of these devices in stores in the U.S. to start handling tasks including scanning inventory and unloading boxes in stock rooms. LG has even demonstrated robots designed to work in hotels and deliver late night snacks to your door.

For now, though, companies need people, even Amazon.
