I believe old style means linear threads and other oldschool UI choices, not just look/aesthetics. That one has tree comment structure similar to all redditlikes, which (I believe) is relatively a recent invention? Have you seen comment trees like this few decades ago?
I think the big problem is the concept of state and corresponding geographical boundaries. If humanity could get rid of geographical binding of territories to states, it would stop all wars, and capitalism would work much better for everyone. Instead of states there could be some kind of unions and they could be represented in different geographical locations, and the infrastructure of any geographical location could be managed by cooperation of unions existing there.
