Packages could be delivered by unicycle drones that swarm together
UPS, DHL, USPS, FEDEX, etc.. ground delivery could go away in favor of automated delivery service. If so a lot of drivers will be out of work. I wonder how these robots will keep packages dry in the rain or snow or how packages will be delivered to the 3rd or 30th floor? Even so, pretty neat stuff aside from the economic impact.
Starting at 0:32, it looks like that little robot is going to hit on her after it's vision overlay turns from red to green indicating an attractive person.
People wanting to trade what they have for what they want, though, is a natural human process.
