The great chasm that divides society will be of knowledge and how that translates to marketable skills.
With the rise of automation, many manual tasks will be performed by Robots and / or Algorithms. Reason being, human capital is not cheap, automation is.
Once a computer model is trained in specific domain, at expert level, it's speed, accuracy and documented audit trail would be no match for average people.
In order to survive the next economy, one must have knowledge and the ability to translate that into a necessary skill that's in demand.
A Data Scientist could train a machine learning model, by feeding it information about court cases, going back 500 years. The Model would learn the logistics, the exceptions, the probability of outcomes over time, and be a source of information going forward, so long its updated over time and verified for accuracy.
That translates to reduced demand for those in the legal profession, like research. Imagine having tons of valid info at your fingertips, in real time, scanning millions of court cases on the fly.
Now, ripple that to scenario to other professions and you see very fast the impact automation will have on society.
Throw in Robots, Self Driving Vehicles, Transportation and Logistics, Food Service, Education and many more industries will be severely impacted.
With fewer individuals able to earn gainful employment, less money flowing through economy, perhaps slow down in GDP, the stress and burden on society could increase as costs and consumer debt rises, the picture becomes a bit more bleak.
There's mention of Basic Income, yet if you begin to review what a global welfare system would look like, you see very quickly there are many holes. As in who will finance a great chunk of society, would crime and black market increase, what would people do during idle time, will population increase or decrease, what chance will offspring have to become educated and find employment.
However. Those that have quantifiable legitimate skills, that are in demand, would find work. Perhaps in technology, or a service that requires on-site tasks, or something creative that requires humans specifically. They will have pick of the litter, luxuries not available at lower rungs, as their skills will be demand.
Looking at things from this perspective, you would imagine any youngster frantically learning everything they can get their hands on, as their future could depend on such knowledge and skills, in order to stay afloat, down the road, when automation and robotics make their way into mainstream society.
And there you have it~!
