I'm surprised at the accuracy of these predictions. Some are outrageous, like the peas and strawberrys sections, but the sections on transportation and especially ready cooked meals are eerily accurate.
What is interesting is the mapping of the 1900 culture onto future possibilities, like the big fruits and veggies, airships, and the people assembling in a hall for an orchestra within a distant one. I wonder where our future predictions are most colored by our own present culture. Personally, I think it has to do with the common assumption that humans will remain the primary decision-makers on the planet. Once we have strong AI, I think all bets are off. It's a scary proposition, but IMO that's where we are pointed.
If we ever achieve a true AI. I think were more likely to initially achieve a ridiculously powerful system which will be able to weigh options and outcomes far more effectively then any human or group of humans ever could but would still ultimately depend on human programmers to guide its goals (thus drastically coloring any outcomes.) But by that point we will beginning to step towards extreme integration of the human mind and machine, thus eventually creating a human network of so that can draw from the processing power of a billion brains, and a billion minds which have instantaneous access to all information to guide their individual goals. Such a reality would create a hyper democratic society while diminishing one of the biggest flaws of democracy (a largely uneducated society who is easily tricked into voting against their own interests.)
