This Talk’s Perspective

Comprehensive monitoring is a major, site specific application.

Major applications become very difficult to replace (e.g. air traffic control, IHC systems)

Worldviews

* What we look through, not what we look at

* Tempts us to think it is the only way to see

* Scientific: what can we know, and how

* Technological: what can we build, and how

* Context

Strategies

* Building and Growth

* Inputs and Feedback

* Planning

* Personality

Building Technology

Coherence
