At some point, in the very near future, there will be intelligent enough AI/,mechanical robots w/e we call them, to control and do 90%+ of all the work-jobs-works humans do/can do. This is a fact.
It's time to start thinking what we gonna do when we reach that point. Saying "x thing will happen so humans will do y works, so it will balance" is like saying" x things happen that destroy the environment so y things will happen to balance and we'll be okey". No it won't if we don't do something about it first.The Internet is full of articles where people who Actively work on the field of intelligent AI have started saying we've already reached the aforementioned point and the replacement has begun.
Factories all over the world are firing people and replacing them with machines. If we had other places to give people work most people wouldn't work in Mcdonalds or plucking chicken feathers factories. The rate of replacement is not equal to the rate new jobs are getting created. Even the job of robot repairer, will need 3-4 people to repair/exam the robots per factory. That hardly replaces the 1000+ people that lose their jobs in the same factory.
It's time we start planning about it. Ideas like less hours/day of work and 2-3 days/week on the same wage a full time job offers should start becoming reality. A new way of thinking and paradigm shift is needed. All people must have access to the basic stuff, like food/clothing/education without needing to work at all. The planning of society should be to point, the new generations especially, towards a way of thinking "You need to work to be active member of society, but not to survive. Survival is guaranteed. Work on fields that will advance yourself and society in the spirit, arts, mind, planning, finding ways of repairing/problem solving and advancing humanity"
More actions that can be taken : birth control in a smart and civil way (less people less need for more jobs) , changing the current societal and economic system (as stated above) etc.
If the above don't start happening soon, we'll reach a point of massive disruption of society. The ones that have vs the ones that dont have. Better to control it than it happen uncontrollably. Same like the environmental issue, we either start fixing and planning else we gonna have a desert Earth in a few generations.
Either way, do or we don't do and let things go on their own, Life will proceed. We only have the choice to either be with life or swim against the current. No need to tell you what will happen if we swim against it.
