The document discusses Walter Benjamin's work "Angelus Novus" and provides analysis of how technologies progress from scientific competence to widespread social adoption. It presents a model where ideation transforms scientific processes into prototypes, and a "supervening social necessity" is needed to move prototypes to inventions. The model outlines stages of performance, ideation, prototyping and a necessity driving adoption. It also discusses how a "law of suppression of radical potential" constrains new technologies through existing social and institutional forces.

14. Types of Prototypes Rejected A supervening necessity has not yet operated and no possible use for the device is seen. E.G. Working telegraph 1816 Accepted Early and incomplete operation of a supervening necessity has created a partial need which the prototype partially fills Parallel The device which will become the parallel prototype is already in existence solving another problem. E.G. Hollerith punch card calculators delayed the computer invention. Partial Designed to perform effectively in a given area but do not.

17. When a communications technology is realised, its growth is suppressed through the constraining influence of already prevailing institutions and other mechanisms. Winston shows how the law can be used as a model for describing the life cycle of many communications technologies. The law of the suppression of radical potential
