Empowerment

“most of society remains one full dimensional leap of awareness and capability behind the few who manage to monopolize access to the real power of any media age …”

“if we take up this challenge [programming], we are looking at nothing less than the conscious, collective intervention of human beings in their own evolution. It’s the opportunity of a civilization’s lifetime.”

Hearers (vs. speakers)

Readers(vs. writers)

Viewers(vs. producers)


Empowerment … with benefits
