Reasons why 21st century won't be that bad?

Along with the things Bridge mentioned, technological advancement usually correlates quite neatly with increases in human well-being. Life expectancy has increased drastically in the last 150 years, modern medicine has saved more people than have died in all of the world's major conflicts, greater stability and quality of commodity production improves health, lifestyle and general social cohesion, etc. For every nefarious application of science there are 100,000 beneficial ones. With that in mind, ALL HAIL GRAPHENE!

Also, if you go by Stephen Pinker's analysis, violence in all its forms has drastically and steadily decreased over the entire span of human history. It's hard to believe, I know, but we're in the best situation that's ever existed for our species and it will likely only get better, if the trend of the last 100,000 years is anything to go by.
