My apologies if i used the word “reverse” along the word “unstopable decline in population growth”. I was more concerned about the “labor force” part of OP. Which i suggested that China can alwaya import immigrants (not citizens) in 5-10 million count to “reduce” the adverse effect of declining population on everyday life of a common chinese. As we see today, China is the fastest growing country for mobile payments, it started introducing robots as waiters in resturants, China is building “factory robots” in 200-300k count per year. So inshort, the need for “labor” will reduce more then half. So (let say) Today China need 30 million labora to do all these business,household,manufacturing etc activities, as per my guess they would need half of that by 2035. So the need for humans to run business is already reduced with the innovation amd automation in industry and households. The other half part will be effected from this decline in labor (skilled and non-skilled) force. Which CAN BE reduced by introducing foreigners and immigrants.
And yes you mentioned Example of japan. Its strange that why the hell they asked those immigrants to pack their bags while they badly needed them ? Still, yes Chinese are not that comfortable with other races, but tell me how open were they in 1980’s ? Can i say China and its society is more welcoming to foreigners then it used to be in 80’s and 90’s ? If yes, then i see this (Opening of society for foreigners) even grow. China is a very sensible country in the hands of sensible peoples. I dont think they will repeat the same mistake that Japan did. China will learn from the mistakes of japs (thats what i assumed in my mind).
Haha. Its not on age. Though age increases the possibility of death but, some die at 10. Some even at birth. Some stay for a century and more. You will be here Inshallah. Just sign for the 72 houris .
You put a lot of effort on this side of story. (Deserve a positive rating). I see that Automation and Unmanned weapons will come with or without the problem of population growth. Humans can not handle diverse information at the same time, machines can do that. So its obvious that Armies will (upto an extent) even inteoduce Machines that will plan strategies for other (soldier) machines. Just like we have CPM and PERT techniques which give us the critical paths and show which way is more feasible to follow. Something in same line will happen in militaries too.
Full servailance of borders through cameras and unmaned weapons , flying unmaned drones above them and robots on pattrol, and an army of 100000 divided in 15-20 locations with supersonic transport planes that can deploy those soldiers in 10-15 minites at any place in china. I see this comming very soon.
I was talking about a more near date , say 2050. Now, you do mentioned “release” of new lands due to global warming and climate change, but, have you considered that many countries (in some proportions of its land) will become uninhabitable due to extreme temperatures ? We have studies saying large part of middle eat will be hard to live on due to the extreme temperature in summers. Similarly, studies shows that maldiev will be under water before 2030. And half of bangladesh, large part of thatta district in pakistan and half of karachi will be under sea. This is just about subcontinent. Global warming will open greenland but it will close large part of middle east and some part of asia for humans.
A settlement on mars is not economically viable and not feasiblr for a population larger then 1000. We dont know/not sure (for know) about the minerals that is worthy to be put in a space ship and transfered to earth which on the other hand will cover the costs of 1000’s of humans living on mars. Moon is a good contestant due to the fact that helium can be sourced from there but thats something that even machines can do in the supervision of 3-5 humans.
Also, tramsformation of mars to current state took 1000’s of years (natural way). If we even comeup with a way to quickly teraform mars, that still wont be sooner then 50-60 years. We wont be able to reduce the fluctuation in day amd night temperature to 30-40 degrees in 50-60 years which BTW currently touches 60-80 degrees ( i assume).
