The other day, Zachary (my 8-year-old) and I were using Google Maps to look at satellite images of New York. The images were of such good resolution that we could see individual people. It's a free service.
July 4th (I think) we launched the space shuttle again, which docked with the space station. It might have come back by now, but it's so commonplace to hurl a hundred tons into space and bring it back safely, I didn't hear if it came back yet or not.
There are initiatives in place to bring technology (cheap laptops, with internet access) into areas of the world that can't pay for them, so their children grow up with a fighting chance to be educated.
Thru the United Nations, "permission" can be obtained for the world at large to tell individual countries that their behavior is not acceptible, without resorting to warfare.
While I'll grant you that every individual doesn't benefit from these good things, and people still starve to death and die from easily curable diseases, the trend appears to be toward better living for mankind, not destruction.
From my perspective.
When I was an angry-god fearing JW, I wondered sometimes if having children "this side of armageddon" was a good idea. Would they live up to his standards? Would they survive "the end"? But now I see a bright future for my kids, I'm very hopeful for them.
I hope you can be hopeful, too.
