This week's Question: This fall, Starship Technologies, an Estonia-based startup created by two Skype co-founders, will begin testing its autonomous delivery robot in Washington, D.C. Washington is the first U.S. municipality to approve ground-based robots to traverse city sidewalks. Starship aims to bring packages from its fulfillment center directly to customers' homes. Ground-based delivery, Starship’s founders say, is an easier delivery option compared to drones, which require compliance with FAA regulations. What do you think?
