Is Your Future Strange Enough?
Prediction 2: Twenty years from now, human society will be exactly the same as it is today. Take the United States, for example. Americans will have the same political beliefs, consider the same matters most important, have the same sexual mores, listen to the same kinds of music (if not the exact same music you like now.)
The first prediction is more likely to be accurate.
Two hundred years from now: The United States will probably remain the most powerful country in North America. It's unlikely to still be the world's most powerful country. (I do think it's likely the US won't be among the weakest nations. The country which exported frankfurters to Frankfurt, hamburgers to Hamburg, and bagels to Warsaw is adaptable.)
If the current major parties survive, they'll be very different from what they now are.
Any music which survives from our time will almost certainly be played rather differently than it is now.
Two thousand years from now: English, like every other living language, will be changed enough so if you were brought forward into that time you'd need to relearn it. Any cities which remain from our time will be much changed.
