Humans, as a group and as a species, are stable . Much more than technology. That is the core idea. If you want stability, look at humans. From generation to generation, human nature doesn't change.
People are people.
However, because technology changes, we have the false notion that we have changed as well. We have not changed. There was love five hundred years ago and there is love now. It hasn't changed much. Pascal and Hailstorm and IBM didn't exist.
