I can see in the future most non-skilled, low skilled and some high skilled jobs will be taken over by computers.
I think transportation will be the first major area to feel automations wrath, imagine a lorry that can operate 24/7, can be programmed to travel at low traffic periods. Can be a mixed hybrid and because of the lack of cabin for driver can be more aerodynamic. I can see Google running a taxi system similar to uber but with fully automated cars, with the option to lift share in peak periods.
Train drivers and bus driver will be able to be replaced and you will have overnight services as lack of extra pay for unsociable hours.
Imagine all the cars on the road being connected and moving out of the way minutes before a ambulance turns up, reducing time.
I think the construction industry will be the second to be hit, I'm supposed there isn't a machine that can remove a old surface , remove the debris and lay a new surface in one continuos method. With new houses pretty much looking the same, I can see 3d printing or automated bricklayers being built.
As the baby boomers die off, I feel we will see a decline in the number of people being employed in the admin, hr and customer service roles as younger people are more used to dealing with machines.
I'm sure farming can be brought into the 21st century, automated plowing or harvesting using gps loggers and positioning. Can even do it at night.
In hospitals I think there is room for automation, automated beds and receptions. Surgeons replaced with controlled arms which don't shake or get tired.
But these are just my opinion.
