Its interesting how some of those predictions are entirely true, even untrue to the extent that they do not go far enough. Fast electric ships to go around the world in a few days, we'll do it in 12 hours and less. Ready made meals to be bought isn't far off either, considering how fast food, TV dinners, etc etc, work. And the the thing about liquid air cooling, well, we don't quite have liquid air in every household but we do use liquid nitrogen in some places to keep food fresh. Still, I find it hilarious that apparently South America would jump at the idea of joining the glorious nation of the US of A!
