What are two characteristics of simple technology and two characteristics of complex technology?

The two characteristics of Simple Technology are : KNOWLEDGE & DEVELOPMENT.  Technology uses and produces technological knowledge. Technological communities endorse technological knowledge as valid when it is shown to support the successful development of technological outcomes.  The two characteristics of Complex Technology are :  ADAPTIVE & NON PREDICTABLE.  Complex Technology is adaptive. They can (re)organize their internal structure without the intervention of an external agent.  Since the interactions are rich, dynamic, fed back, and, above all, nonlinear, the behavior of the system as a whole cannot be predicted from an inspection of its components.
