Even where people in different cultures agree they may all have gone wrong.

It is hard to tell if capital punishment has such an effect. And even if, in some contexts it has (such as in the American South with a very high incidence of murder), this effect may very well go away if a decent welfare state was replaced for the existing social order.

You are only allowed to treat the content of your intuition as evidence if the intuition stays after you have exposed it to cognitive psychotherapy; in some cases you have to reject it even if it does indeed stay.

There comes a time where next to everyone will resort to techniques that enhance cognitive, mental including emotive, physical, and other capacities. When this has happened, if not before, the ban on doping in sport will have been lifted.

My conjecture is that most people will refuse to let go, even when their lives have become boring (at least in comparisons with possible lives lived by new generations). If this happens, there will eventually be no room for new generations. A kind of collective irrationality will lead to a bleak life for the last generation that decides to stay around. Unless we put and end to the human race (through global warming, for example), before this happens, individual egoism will block the path to a better world.

Different areas present us with possibilities to test different theories.

The possibility to go on indefinitely with our lives may become a reality and it will present us with a temptation.
