Tough question. To see how tough, imagine if the year were 1900, and you were wondering what the world was going to look like in the year 2000. Would you have imagined the two world wars, and fall of the European Empires? Would you have foreseen te revolution in transport and lifestyle? The rise of technology and innovation? Probably not.
BTW. from images created around 1900 about the future, most underestimated how culture and lifestyle would change (future people would sill dress like they did in 1900) and overestimated how much technology would change (living under the oceans and in the air?)
So if we ask what the world will look like in 2119, we can be confident in only 2 things. It is not going to look like it does now. Culture is likely to keep changing radically. And any predictions we make about how it will change are likely to be off by a mile. We probably over-estimate what tech will do to change us.
Having said that, some of us are more competent to make these predictions than others. And George Friedman is one of those more competent dudes. He has a sort of smug way of talking, which can be off putting. But when you listen to what he is saying,you have to admit that it is logical George has written a book about the next hundred years, and in this interview he answers questions about his predictions. I found his prediction about space based solar energy generation to be pretty interesting. Enjoy!
