Honestly, I have no idea. I admire your intellect and your ability to grasp that difficult subject of human destiny, but I was mainly wondering about shorter term events. I am not 20, not even 30, not even 40 ... fucking hell I am not listing the rest ... therefore I was thinking what's going to happen until the year 2032 turning point that Armstrong defined. Around that time the automation, robotics and IoT adoption will make the 50% of currently known jobs obsolete already. The governments will have to deal with that transition and large amount of unemployed workforce. I know, I know, the knowledge economy will create new opportunities in other areas, but still, there will be a radical shift in the society terms of employment opportunities as well as about employability of the workforce (many, lot more than today simply won't be employable at all). The industrial revolution 200 years ago caused quite a lot issues, but this will be a significantly bigger shift.
I`m also not 30 yet, I`ve learned about humanity pretty quickly. It's really not that hard, plus I got a big thirst for exploration and understanding.
I could probably forecast that humanity is not fit for survival in the very long term, it will probably be wiped out in the coming 1000 years, however in the short term it will probably be a chaos too.
The automation is a big problem, and socialism will grow. With that crime and social distorder will too.
I can hardly doubt this economy will last more than 5 years, and when the welfare runs out, and no job possibility will there be, many people will get hurt.
And I don't even think war will come, because the weaponry is too dangerous. I think it will be just the mere civil disorder and famine that will wipe many people out.
I dont want to be a doom forecaster but I think if the economy really gets destroyed, at least 3 billion people will be wiped out.
