Asimov's science ideas sound outdated in some cases because they became science fact. For example his 1945 proposal on communications satellites in geosynchronous orbit ... Www.lakdiva.org/Clarke/1945ww as quoted in Wikipedis. First successful satellite launch to Earth orbit was Sputnik in 1957. Stuff Asimov proposed 71 years ago is the basis for Pokemon Go ...
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.
