I suspect you've got Clarke and Asimov mixed up there. The article that you linked ( http://lakdiva.org/clarke/1945ww/ ) was written by Arthur C. Clarke.
Clarke was a bit more grounded in the harder science fiction disciplines (Fountains of Paradise with its space elevator) while Asimov tended more to the software side looking at psychology and sociology, empires and the people.
