The Chinese are learning from their Japanese counterparts and are already pressing robots into military service for fighting and storming buildings and are considering them for use in care homes, as the Japanese commonly use ASIMO robots for toileting, turning patients, cleaning, showering and bed turning.
With AI and expert systems in robots, you will not need people for street cleaning, office cleaning, lorry driving, train driving, inbound call center/customer service work, or simple administration.
Lawyers and accountants doing basic book keeping and non-contentious work, will not be needed either, and the potential of robots plus AI, plus 3D printing will be to eliminate 50% of American jobs by 2033.
Governments need to be calculating what balance of people in work are needed to create sustainable markets and they need to be preparing the public as best they can for the world that will emerge from this instead of not talking about it.
An immediate use for flying robots that can open doors would, in my my mind, be to go inside larger military drones and then burst out without the need for parachutes to hunt down Jihadis in inhospitable places across the world and kill them. The saving of police man hours and the time of courts and other professionals trying to “understand them”, arrest them and imprison them would be saved. There would be no place for such people to hide.
Peaceful use of robots would be in farming, dock working and food production whereby people now engaged in crippling manual work would be freed from it.
Areas now devoid of policemen, such as my own town which has no police station, would be patrolled by robots, surly supermarket checkout staff, warehouse staff and parking attendants would be similarly replaced and robots could be used to look after a group of Adult Social Care recipients in several different homes without the need for a car and the risk of getting or giving someone flu,a cold or some other affliction.
