How can you be so sure? 100 years in modern era is very very long period of time, and in 21st century it will be huge. You cannot predict what is going to happen 10 years from now and you think you can plan everything for 100 years ahead. That won't happen.
To put you in the perspective, get this: modern high-energy industrial era we're are living in now is only about 100 years old. Globalized economy is even younger, probably about 20 years old, 30 years at max. The stuff you see around is very new. Try this simple thought experiment. Imagine yourself in 1910 trying to predict and plan the future, be sure to forget what happened during 1910-2010 and act on the "newest" knowledge of 1910. History is too volatile and progress is exponential, unless you somehow oppress everyone and stop advancement artificially, like in some "1984" dystopia, and even such dystopia wouldn't last forever.
The economy was globalized in 1910, and was deglobalized in two huge steps, once in 1914-1918, and then finally and for sure in 1929-1931.
This new era of globalization was a repeat of that time. It's possible we are at the beginning of a new era of deglobalization again. Whether we're in for a repeat of either 1914-1918 or 1929-1931, or of the entire goat f*ck that was 1914-1945, well, I don't know and neither does anyone else, of course.
Also, that era proves that while technological progress may be exponential, human progress is a bit slower.
