That's an interesting question! Can anyone suggest a good way to estimate this? I'd estimate the odds at around 80%-90%, but I don't have any coherent working

That's an interesting question! Can anyone suggest a good way to estimate this? I'd estimate the odds at around 80%-90%, but I don't have any coherent working to back that up. Note that very few human institutions have lifespans of 1000 years or more: a few universities and the Catholic church. I'd hazard a guess it is highly unlikely that the US exists in 750 years.
