I may be incorrectly inferring that you think this is a good thing, but "traditionally tribal humanity" were constantly at war with one another. I'm not sure that's something we want to go back to.

Yes, it was (and some places, sadly continues to be) the ultimate horror that people can visit upon each-other.

Suffering it, over and over and over, was what led humanity down the natural, logical path to becoming civilised and cooperative.

It's the lesson we need to learn well, if our self-appointed badge of Very Intelligent Species is to actually mean anything more than a pointless, neverending game of forming factions and battling other factions.
