I'm really having a hard time understanding your criteria for humanness.
You mention "modern humanity" above. Except for the last few hundred
years I don't think you have characterized human history very well at
all. What about non modern humans, were they human? And what about
civilizations that do not display these characteristics, are they human?

Some (not me) might say the Amish are also a striking example of
lackluster stagnation.
