If you look at the past and how long super powers last, I think its a matter of fact that in 100years AMERICA will no longer be a super power. If you look at obesity, drugs, hatred, violence, are aging infrastructural, lack of jobs, lack of money, death, mental illness, sickness, crime, jails, mental hospitals... look at it all just multiply it by 10. Things are not getting better... people are not doing better. Some people live longer but the amount of more people in jail, more people hooked to drugs, more crime, more evil...
in 100years nothing around us will matter or be important, what will be important? Getting food on the table....
Again I repeat CHINA. China which has a huge amount of people and has lasted a lot longer then america will probably be the super power..
thats what i think
*matter of fact* I think things that are bad now will be much much worse, and as a result the bad in people will come out.
