Along with racial equality and the late bloom of women's rights, future generations will have to explain how, in the past, gays were misunderstood and publicly humiliated for loving each other, and, eventually, how they stood together and conquered stupidity and hypocritical hatred, and fought their way out of marginalization.
If future generations are to remember us more with gratitude than sorrow, we must achieve more than just the miracles of technology. We must also leave them a glimpse of the world as it was created, not just as it looked when we got through with it.
The most important thing about global warming is this. Whether humans are responsible for the bulk of climate change is going to be left to the scientists, but it's all of our responsibility to leave this planet in better shape for the future generations than we found it.
We have a moral responsibility to save wild places like the arctic refuge for future generations, and that is why our country has remained committed to its protection for nearly 50 years.
Looking ahead, future generations may learn their social skills from robots in the first place. The cute yellow Keepon robot from Carnegie Mellon University has shown the ability to facilitate social interactions with autistic children. Morphy at the University of Washington happily teaches gestures to children by demonstration.
My own view is that being a vegetarian or vegan is not an end in itself, but a means towards reducing both human and animal suffering and leaving a habitable planet to future generations.
Each additional idea is a gift to the future. Each additional idea producer is a source of wealth for future generations.
As long as there are people in education making excuses for failure, cursing future generations with a culture of low expectations, denying children access to the best that has been thought and written, because Nemo and the Mister Men are more relevant, the battle needs to be joined.
Whether they run a record company or a grocery store, every boss will tell you you're in big trouble if you're borrowing more than you can ever afford to pay back. Delaying the pain for future generations is suicidal. We've got to start getting the deficit down right now, not next year.
We owe at least this much to future generations, from whom we have borrowed a fragile planet called Earth.
