How many years do you think the idea of nation state would exist

I am really curious...since in most asian countries..it would came around 70-80 years...do you think it would exist for 1000's of years like autocracy or monarchy?..but honestly seeing everything is speeding up in the last 100 yrs...humans started using tools 800000 years ago...but only made proper guns 100 years ago...so..we are growing at an exponential rate ...do you think all humans in the world could unite to colonize the multiverse..or would divide ourselves a lot more?..I think india is gonna have a lot more influence as time goes in the future..what do you guys see for the future of the world...I put this in askindia.. because I was curious about Indians opinion on this question
