Since then, every 30 years this number has doubled. 1 billion by 1930, 2 billion by 1960, 4 billion by 1990, 8 billion by 2020.
30 years must be a rough estimation for the average couple on earth to have children, and we need more births to remain productive and grow the economy. However, I do not believe that it is sustainable to have another population doubling in 30 years. We would be 16 billion by 2050 and 32 billion by 2080.
What will happen?
I believe that AI will take over most jobs within 10 years, and the global elites will find a way to drastically reduce global population.
Who will be the leading global superpower in the future? I doubt it would be the USA. On the other hand, Israel needs the USA to defend itself and I believe that they are now looking for a way to solve the debt problem and keep the USA as a superpower. They are very aware that without the USA, they are utterly defenseless. So that gives me hope. I believe that crypto will be the gateway to wipe out the 36 trillion dollar debt problem and switch to a new set of rules in which the USA remains dominant.
I do not believe that governments will be able to pay pension funds to anyone in the future, in the monetary system as it is now. Hence why I am not saving money for retirement. I invest and diversify, and intend to be self sufficient by growing my own crops.
Will we move to a different planet? If so, it must be Mars.
I'm excited about Musks dream to make Mars a habitable planet.
I don't think moving to Mars is something most person seem to be too excited about, first of all the population of the world today has not even gone one quarter to fill up the space on Earth, we've not been able to inhabit the nooks and cranny of Earth to it's brim, why will there be so much excitement to move out of Earth when there are lots of places we still haven't explored as humans. I feel Elon musk plan to make Mars habitable is to fulfill his long desired passion, so people can easily go out of space and see how another planet outside Earth looks like, but deciding to stay there and start a family, is a decision I don't think humans are ready to take anything soon.
