Why NBIC? Why human performance enhancement?

A 2001 U.S. workshop with the title "Nanotechnology, Biotechnology, Information Technology and Cognitive Science (NBIC): Converging Technologies for Improving Human Performance" introduced the convergence of various sciences and technologies based on their nanoscale properties. It highlighted BIC as the science and technologies converging on the nanoscale. However many other sciences and technologies with nanoscale components exist, such as chemistry and material sciences. Furthermore the workshop chose human performance enhancement as its case study of application despite various other possible applications that could have been chosen. This paper addresses the questions why the workshop organizers (a) introduced nanoscale as a convergence concept, (b) chose BIC as the convergence examples and (c) chose human performance enhancement as their application. The paper provides some thoughts as to the success and consequences of that strategy.
