The fact of the matter is that naysayers are sometimes correct. I still haven't seen the personal helicopters, and jet packs that were supposed to be ubiquitous by the late 20th century, although the self-driving autos are making an appearance, albeit a few decades late. No colonies on the moon, or broadcast power, as was forecast. The huge space stations and tours to the moon are more than a few decades from reality.
