This sounds like darwinism. Evolution is a law of nature, not a law of society.

What you say is true for species that don't have language or civilization. But since humans have technology, evolution happens in our minds, not in our DNA.

And new ideas don't necessarily require new people.

> radical decisions

Like what?

> People living longer will stay in power longer and keep the status quo alive.

What kind of prediction is that?

> Like what? Take any norm breaking innovation in the pass 2000 years. Any idea that sounded arcane at its time: Earth is not Flat, its not the center of universe, light is a wave and a particle, etc. Perhaps decision was not the correct word to use, "ideas" would be better.

> What kind of prediction is that? A prediction like any other. I think we tend to become risk averse as we age, risk averse people don't like changes, without change you don't have a chance to fail, or succeed. If people to live longer I would think that every other stage of life would start to stretch. Take presidency as an example, its a four year cycle. If life expectancy was 200 years, would it not make sense to have presidents for 8 years? Would you retire after 30 years or 60 years?

I don't think so. You're generalizing. Actually I would think that the opposite can happen.
