Variety and diversity

Esko Kilpi made a series of tweets today that I wanted to collect in a single post:

Unlike mechanical systems, human systems thrive on variety and diversity.
An exact replication of behavior in nature would be disastrous and seen as neurotic in social life.
The Internet changes the patterns of connectivity.
The Internet transforms our understanding what “local” is, makes possible wide participation and new enriching variety in interaction.
All human systems are connected and connected systems cannot be understood in terms of isolated parts
The unit of analysis is now communication and emergence, not entities.
The perspective of network science views knowledge as socially created and socially re-created.
Management literature typically emphasizes individuals and locates explanatory power in their personal properties.
The potential of social media cannot be realized without a very different epistemological grounding, a relational perspective.
Independently existing people and things then become viewed as co-constructed in coordinated networked action.
