So, when two multi-lingual men or "petman" robots meet on a Paris street decide to argue and resort to fisticuffs, they must know that their lack of agreement may be costly. If it happens too often in a day or within 95 years you wonder what is causing intelligent men to resort to global conflict; so much bad water and blood in 95 years over vhs vs. beta but beta was a more efficient tape with less plastic pollution. They could be arguing about the universal wisdom of water as a necessity for the future if human life. Maybe they are arguing about the purpose of copulating. Maybe they are arguing about the best way to skin a moose or on the best way to make a devil's food cake. Maybe the devil's food cake can be made with neopolitan icing and cake filling; that is flesh, chocolate and vanilla. But, who knows. Hopefully, it's not about who has the best smart phone or swiss camping knife. That would be an ego battle amongst highly intelligent beings. But, who knows. Maybe, they could just get together, shake hands and open a lot of corner stores where people can just walk to the corner in a rebuilt community. People will always buy a car. Selling cars these days is not the issue but you need a community or yearn.
