When I was a kid, I assumed that in the future things would get better and better until we were all driving flying cars and playing badminton with space aliens on top of 500-story buildings. Frankly, I kind of counted on this happening. But now I don't assume that we'll just keep going up anymore.
Note: Wilhelm Furtwangler's last name is typically spelled with an umlaut over the 'a' character. The npr website does not support characters with umlauts over characters. A variation of Furtwangler's name without the umlaut is spelled Furtwaengler.
Wilhelm Furtwaengler's name may be hard for Americans to pronounce, but the reason this great conductor isn't so well-remembered here is that he chose to remain in Germany during WWII, though he was never a member of the Nazi Party, and was exonerated by a postwar tribunal.
