dangerous=not safe, since I don't know it, I don't feel safe

most of those who think novelty is "benefiting" have died a painful death. Those who survived and have off-springs are smart enough to survive the danger of novelty.

As you may realize now, there are four kinds of people,
stupid and afraid of novelty
smart and afraid of novelty
smart and embracing novelty
oh, my mistake, there are only three kinds of people, the fourth kind doesn't exist any more.
