Conservatism & Immortality
Over time social change takes place because older generations die off so that the younger folks who are more open to new ideas have the (political) power. Now that the baby boomers are starting to reach in age are we going to see a massive shift in political opinion within the next 10-20 years?
Also, medicine is increasing the human life span incrementally, and our generation might be the first to live regularly more than a century, or even achieve pseudo-immortality. How will societal change occur?
