Our world today is filled with unmanned systems, and they seem to become more and more popular, while manned systems are on the decline. Everything from ATM machines to drone planes, we see more and more about unmanned machines running tasks that human are not required to do.
We have surveillance cameras along the borders, and even self checkouts at grocery stores. Banking can occur 24 hours day without the need of a human bank teller. There are robots being used to make portions of cars, and even robots being used to pull orders for big box retailers who need to keep up with the speed of the internet.
Once thing is certain, we will be relying more and more on technology to handle tasks that humans used to do.
