Thank you for all of your comments and wishes. I know I'm 10 years late in replying, and I apologize. I never made it back to the year 2038, as I had hoped for. I'm now retired in Washington State.
World War III had nothing to do with ignorance and hatred among the general populace. It was a war over petroleum supplies, which was fought by, shall we say, The Powers That Be. As strange as it may seem, oil still powered most of the world in the 2030's, although it started to dwindle in supply that same decade.
You have gifted insight, Hatsune. I agree. There is not a lot of hatred today. Most of the hatred is being generated by multi billionaires and trillionaires - the people who wag the world. They are so incredibly wealthy that their lives have become so complicated. Never trusting anyone, because too many people want a piece of their wealth. Even family members. Since they bought virtually everything they wanted, the only thing left they want is power. Greed, and the desire for power create most of the world's problems. Once the oligarchies amass all the money and material assets they want, they become bored, and sometimes, believe it or not, grow jealous of your simple, average, everyday Joe out there. Because Joe's life is a hell of a lot less complicated. Joe is much happier strolling down the dirt road with a pole over his shoulder, ready to do some fishing at Fife Lake. So, the oligarchies start messing with Joe's life to make him unhappy. And the general populace's lives.
I meant ignorance as in religious beliefs, science and technology. The men and women were treating each other with more respect in the 2030's, and there was less prejudice among different races, too. And yes, people were even lazier in the 2030's due to AI and other technological advancements.
