Germany never becomes the scientific and mathematical hub of the world as it once was. And it won't for the foreseeable future. So yeah, 100 years is on the optimistic side.
This is an under-rated point. Prior to WWII, most people pursuing doctorates in scientific fields learned (at least a little) German. Because German was the language of science.
Not anymore.
I fear that we're all going to need to learn Chinese.
