Way back in the mists of ancient times, about 1970, a myth arose in minds of primitive men and women;

The new Internet was like a telephone and could connect anybody to anybody.

This 'peer-to-peer' idea was good thing. It felt exciting and democratic. It remains a fantastic leap for humanity, worth defending to the death.

However, for some - a possibility once becomes a necessity unto the limit - that is to say the idea that;

"occasionally anyone could talk to anyone"

silently transformed into the idea that

"everyone should talk to everyone all the time"

whereas in fact

"most people don't want to talk to most people most of the time".

That is a problem at the intersection of people, technology and culture. As the earliest culture-shock pundits predicted, we still haven't really worked out what we want to use this technology for.

It would be best not to optimise too early, to leave our options open and not let any one model dominate development - which is the theme of resilience through diversity in the OP.
