I believe Newton’s first law of motion applies to predicting the future - a body remains at rest or continues to move at a constant velocity unless acted upon by an outside force.
In other words, everything will continue as in the past, until an outside forces changes it. This unexpected outside force is often refereed to as the Black Swan Theory.
While we can use the past to predict trends, we can not truly predict the future for the simple reason there are too many variables and is by definition unpredictable.
I think it would be safe to say an event will occur that will change everything. Trying to pin down that particular event is what is impossible. It could be war (it has been close to 70 years since the last major world war, we are closer to another than many would like to think about). Or, it could be a truly world wide pandemic not seen since the early 1900s. Or it could be spontaneous revolutions in a bunch of different countries with the populations over throwing their existing governments.
Regardless, there will be a large loss of human life and a disruption of trade. And that is my point. When you have world wide trade and every nation’s economy is based on that trade when it is disrupted, there will be chaos and perhaps famine.
People have become to reliant on technology. If that technology were to disappear (if the power gets shut off) most will not know what to do.
I do not see a happy future for mankind.

I believe you are right on the mark, like Newtons law i think, every thing that goes up must come back down.
The Bible tells us there is nothing new under the sun, every thing that will be has aleady been.
