Personality 2: digital technology critic

The promise of digital technology is impresssive, however, some believe their are limits and others believe humans need to set limits. For example, nanotechnology proponents claim that if researchers could design and build structures at the scale of single molecules, the world of possibilities would be metaphorically huge: drug factories the size of pinheads, computers in the brain to aid memory, robots moving through the bloodstream to repair internal injury or disease. One opponent stated; "It would change what it means to be human,"

Personality 1: Not enough energy critic

The energy required for digital technology has caused concerns from the beginning and future projections of energy consumptions have force many to suggest aborting digital technology development. For example, a opponent has stated; "It's a mistake to extrapolate exponential trends indefinitely, since they inevitably run out of resources to maintain the exponential growth. Moreover, we won't have enough energy to power the extraordinarily dense computational platforms forecast, and even if we did they would be as hot as the sun."
